Northian grammar

Northian grammar is highly synthetic.

Overview

Ablaut

Ablaut is a system of vowel apophony, altering the quality or quantity of vowels but not their meaning, that is inherited from Proto-Nordic-Northian and ultimately Proto-Erani-Eracuran. It affects nouns, adjectives, adverbs, and verbs in Northian. Though ablaut was a regular process closely tied to accent in the reconstructed proto-language, by Galic times new ablaut formulae are no longer being made, and only a few ablauting formulae remained productive. Moreover, existing formulae have been disrupted by sound change and both general and sporadic analogical replacement. The result that surfaces in Galic Northian is a rich yet unpredictable set of alternate morphologies that confuses both modern readers and, often, even ancient Northians.

In nouns, there are three main ablaut patterns that Northian inherited from its ancestors, in the discourse of PEE called acrostatic, proterokinetic, and hysterokinetic. All three patterns are preserved in Galic Northian to one degree or another, summarized below. The proparoxytone category continues the PEE acrostatic pattern and its characteristic o/e ablaut, though synchronically this ablaut pattern is but attested in a few forms of a minority of nouns (e.g. nemə̄ṇġ gen. of nomə̄), the majority of proparoxytone nouns having arbitrarily generalized either o- or e-grade across the paradigm. The paroxytone group largely continues

These processes have occurred to the greater extent in the Epic language, but there the word forms were subject to more rigorous regularization.

Noun endings

Athematic

The following chart recapitulates the ordinary endings of athematic nouns in Galic Northian. Because the ablative is syncretized in the singular with the genitive in all athematic declensions and with the dative, with or without the instrumental, in the dual and plural, it is usually not listed separately in grammatical tables for athematic nouns.

Forms are often unpredictable and variable under the influence of ablaut, laryngeals reflexes, analogy, vowel contraction, and compensatory lengthening for illegal consonant clusters in coda position. All endings are subject to modification according to the suffix. OX stands for the oxytone group of patterns, and PX for the paroxytone group. Certain neuter nouns do not take plural endings but collective endings with a lengthened stem; these nouns are not formally predictable. Because neuter nouns always have the same nominative and accusative forms, only their nominative endings will be listed, and in grey.

	Athematic endings
	Singular		Dual		Plural	Collective
	OX	PX + PP	OX	PX + PP
Nominative	-V̄-Ø, -s, -å, -Ø	-s, -Ø	-ē, -ī	-a, -V̄, -V̄R-Ø, -ī	-es, -iš, -a, -V̄R-Ø	-V̄-Ø
Vocative	-Ø
Accusative	-m, -um, -əm, -ə̄m				-V̄n, -əṇġ, -ə̄ṇġ
Locative	-i, -eC-Ø	-eC-Ø	-ō	-o, -i̯-u	-ho, -šo	-eC-Ø
Genitive	-ō	-s, -V̄s, -V̄n, -V̄ṇġ	-ōs	-uš, -u̯-ō	-õ	= sing.

Instrumental	-ē, -å	-C-a, -V̄R-Ø			-vi̯as

A general discussion of the athematic declension cannot omit to mention that many of these divergent forms are conditioned on phonetic change, but so too there are divergences because the proto-forms themselves were likely divergent. Animate (= masculine and feminine) nouns may have been in the proto-language sigmatic in the nominative singular, that is ending in *-s, or asigmatic, that is without final *-s and instead taking a lengthened final vowel. The source of this lengthening is disputed: some authorities regard it as a consequence of a final *-s dropping after a resonant, but others hold it had no *-s originally and attribute the long vowel to ablaut variation sensitive to the morphologically strong case. In the case where a universal *-s as a designation of the nom. sing. is not accepted, some propose it is instead a designation for those terms originally neuter in gender used as an animate noun.

The view that nom. sing. is not characterized by final *-s is more often supported by scholars specialized in Northian, since this phonetic change (dropping final *-s after resonant) is attested later than the proto-language, which militates against its presence there. Nevertheless, final *-s has definitely been inserted to animate nouns quite broadly but haphazardly in prehistoric Northian, so there is no obvious pattern to its distribution. We may distinguish three situations in Northian as to the nom. sing., stems ending in vowel, in resonant, and in non-resonants. Final *-s where present is always preserved after *i- and *u-, and their absence there indicates a noun is obligatorily neuter. Final *-s seems to have been mostly absent in resonant-stems, whose nom. sing. takes the long grade instead (i- and u-stems never have long grade in the nom. sing.). After consonants their distribution is not predictable: nepōt "grandchild" was asigmatic, but nohs "night", pontōs "path", and nouns ending in -tāθs certainly had *-s, which is altered after most stems.

The vocative consists of the bare strong stem in all cases. Where the stem had *-s it is dropped, and without *-s the stem is in the full grade or short-vowel grade. In the proto-language, the accusative ended in *-m. In consonant stems it is vocalized as -m̥ > PNN *-um. After resonants, it is generally the ending *-m̥ that is vocalized as PNN *-um. But in Galic an unaccented ending *-um is always altered unless preceded by *y, to -ə̄m if the preceding syllable is light, and the short variant thereof, if heavy. Where the ending is a vowel or a glide, the bare ending of -m is found.

In the genitive, dative, and instrumental (oblique) cases, the acrostatic, proterokinetic, and hysterokinetic ablaut patterns in various suffixes give rise to different endings. The ending *-os > Galic -ō is proper to the OX nouns, but in the Epic language it is often applied to other stems; in either dialect, the ending rarely interacts with the stem and stays mostly visible. The proterokinetic and acrostatic ending was PNN *-s. After a full-grade ending, expected in a PX pattern, it is preserved where the suffix ends in a vowel as in ēš < *-ei̯-š and -eu̯-š, and the same for PPX patterns. After a resonant it is usually dropped and causes the preceding vowel to lengthen, cf. -mēn < *-men-s, but -ō could be re-attached to it when metrically convenient. After a zero-grade ending, in an PPX pattern, the fate of *-s is varied. In consonant clusters it usually caused deletion of intervening consonants, e.g. PNN *nekʷts > Galic nehš. After PNN *-un it generates -ūn, after *-um it was -ə̄ṇġ, after *-ur and *-ul it was -ūš.

The dative ending in OX is *-ei̯ > -ē; as the gen. this is the most often found ending beyond its natural environment. In PX final *-i becomes -e in Galic and causes some previous vowels to mutate, i.e. *eC > ei̯C and *aC > -ai̯C <ae>. Yet in the cases where it directly occurs after short vowels, it remains -i.

Thematic

The chart below illustrates the ordinary endings of the thematic (o-stem) declension of Galic. Because accentuation difference categorically does not trigger ablaut in o-stem nouns, their endings do not vary according to their accentual pattern, which is lexically fixed on the same syllable. Additionally, the presence of the theme vowel e ~ o obviates, in most cases, the resolution of consonant clusters and consequent irregularity in surface forms. With the exception of a few fixed athematic patterns, o-stem is the primary productive pattern in the Epic language.

	Basic thematic endings
	Singular	Dual	Plural
Nominative	-ō, -om	-ō, -oī	-ōs, -ā
Vocative	-e
Accusative	-om		-ōn

Verbs

Stems

The relationship between verb-stems and endings they receive are as follows in the Galic language:

	Present stem	Aorist stem	Perfect stem
Primary endings	Present indicative tense
Secondary endings	Injunctive tense	Aorist indicative tense
Imperative endings	Imperative tense	Aorist imperative tense
Future imperative endings	Future imperative tense
Perfect endings			Perfect tense
Perfect imperative endings			Perfect imperative tense

From each root, which is agnostic as to part of speech in the proto-language, can arise multiple stems classified as present, aorist, or perfect, differentiated by their affixes. To these stems are attached endings to constitute the finite verb, which conveys tense/aspect, mood, voice, person, and number.

Evolution

Northian is one of the few Erani-Eracuran languages that retains multiple productive ablaut patterns in nouns, though hysterokinetic endings have gained ground in many stem-classes at the expense of proterokientic and acrostatic formations. This tendency is attributed to surface consistency in hysterokinetic endings, which are regularly accented sing. gen. -ō < *-os and dat. -ē < *-ei̯.  The proterokinetic and acrostatic endings tended to disappear through the erosion of final consonants and unaccented vowels. After most consonants, final -s disappears, lengthening the preceding vowel and modifying consonants in several ways, while final -i lowers to -e and causes preceding -e- > -ei̯- and -a- > -ai̯-. The places where *-s and *-i remain in situ are the i-, u-, ī-, ū-, ē-, and neuter n-stems (*-i only).

Despite recession, former proterokinetic nouns appear from "irregular" nouns that either retain proterokinetic endings, accentual positions, or both. The hysterokinetic ending is often simply appended to the stem already reflecting the proterokinetic ending, e.g. Epic pau̯ḗnō from Galic pau̯ḗn + hysterokinetic gen. ending -ō, whereas a "true" hysterokinetic noun would have ending -ṓ and not a full-grade suffix.

In the dual nom. the preference for hysterokinesis was evident, and only neuter nouns were consistently inflected proterokinetically, probably because it had a distinct ending -ī that resisted phonetic assimilation. Where the stem ended in a resonant, the animate ending *-ə disappeared by regular sound change and cause compensatory lengthening. This created an anomalous stem with long vowel where it was not expected (only in the nom. sing. was long vowel expected). When this happened, only stem and root ablaut distinguished it from the inst. sing., so if the stem had lost ablaut, as often was the case, it would become identical to that form. In the other dual cases, however, proterokinetic forms survived for longer, but once the hysterokinetic form was introduced to the nom., it too often crept into the other cases (especially in the same speaker's utterances).

Some linguists propose that Galic poets retained more archaic patterns for their flexibility in verse, as full-grade endings generated heavy syllables and zero-grade generated light syllables. It is criticized that metrical considerations are absent in common speech, so it is questionable if ablaut patterns were retained there as long as it did in the poetic language. Indeed, while younger Galic metre may have been written as late as the 5th century BCE, productive proterokinetic patterns in Epic verse has been whittled to the i-, u-, and n-stems. The acrostatic pattern has been a vestigial, closed set since the earliest stages of Northian canon—it seems hard to avoid this conclusion if a term as basic as E.Nr. maetūr (G.Nr. mētūš) "mother's" was disappearing from children's speech in favour of maeθrō. Acrostatic n- and s-stems were no longer viable even while their proterokinetic cousins were. On the other hand, acrostatic formations have spread prehistorically to proterokinetic ones, in the ins. sing. of i- and u-stems, which often show zero-grade ending where full grade is expected.

Awareness of multiple ablaut patterns persisted well into the period of the Late Canon, attested in the chastisement of children who substitute oxytone endings for their paroxytone counterparts. Ancient grammarians divided nouns into two kinds based on the position of the accent in the gen. sing. form. The oxytone group includes all nouns that have accented endings, and paroxytone group, nouns that have unaccented endings. The grammarians teach that this predicts the endings and accent positions in other forms. Modern scholars accept that some parts of their teaching correctly identifies the contrast between proterodynamic and hysterodynamic endings, but the shape of the stem was not connected by the ancient grammarians to the position of the accent. Acrostatic nouns were considered an irregular type of proterokinetic nouns and not as its own class.

Nouns

Classes

The principal classes of nouns are discussed first. The following chart lists the stems and accent patterns that are attested in Galic Northian, as well as the genders of attested nouns. A green cell indicates that the attestation of a stem-accent paradigm is solid (five lemmas or more and paradigm more or less complete); a yellow cell indicates a marginal attestation (one to four lemmas or paradigm incomplete); a red cell indicates no or only dubious attestations.

	-C	-m	-ns	-mn	-n	-r	-l	-s	-os/es	-i	-u	-h₁	-h₂	-ī	-ū	-r/n	-d	-t	-nt	-woḏ	-ā	-o
OX	M/F	F	M	M/F	M/F	M/F	All	M/F	N	M/F	All	M	No	M/F	F	N	M/F	M/F	All	All	F	M/N
PX	F/N	No	No	N	No	M/F	No	No	N	All	All	No	F	F	F	N	N	No	No	No	No	No
PPX	F/N	Yes	No	N	No		No	F	N	All	All	N	No	No	No	N	No	All	No	No	No	No

As will appear from this schematic, there are few noun classes that exhibit all three patterns that continue the ablaut patterns of the proto-language; rather, there was a strong tendency for noun classes to coalesce on one pattern identified with the stem, or for masculine and feminine nouns to coalesce on one pattern and neuter nouns on another. In the latter case, neuter nouns are almost always identified with the paroxytone pattern, and masculine and feminine nouns with the oxytone. The exception is for i-stems and u-stems, where a considerable portion of masculine and feminine nouns inherit acrostatic patterns from the proto-language. In other cases, the skewed distribution of gender is inherited from the proto-language, as in the case of ī- and ū-stems, which historically are combinations of *i-h₂- and *u-h₂- and therefore take their feminine gender and proterokinetic pattern from the h₂-stems in PEE. Some nouns of this class have been further elaborated with an -s ending, which brings about the oxytone pattern and can be masculine in gender.

With the r-stems the acrostatic pattern has bled into the PX pattern.

Consonant-stems

The category of consonant-stems consist only of those that end in -p and -k, while resonant- and vowel-stem root nouns are discussed in their own categories, whether suffixed or not, as the phonological processes that apply to them generate similar results.

The noun āps < PEE *h₂ēp-s "river" is often the poster-boy of the Northian nouns due to its straightforward stem and clear ablaut alteration between ā ~ a. op "force" is used for neuter nouns, displaying PEE e ~ Ø ablaut > Galic o ~ Ø. Both these nouns are of the OX type, displaying an accented genitive ending in -ō < PNN *-os.

	sā āps, "river"			tod op, "force"
	Singular	Dual	Plural	Singular	Dual	Plural
Nominative	āps	āpē	āpiš	op	opī	opa
Vocative	āp
Accusative	āpum		āpə̄ṇġ
Genitive	apō	apōs	apõ	pō	pōs	põ
Locative	ai̯pi	apō	apšo	ei̯pi	pō	pšu
Dative	apē	apmō	apmuš	pē	bmō	bmuš
Instrumental	apē			pē

Another noun used for the same purpose is aps "river".

While o/e ablaut is considered canonical for PEE root nouns with acrostatic inflection, neuter nouns in Northian show neither o/e ablaut nor PP inflection: they are, for an unknown reason, all PX.

	tōd osta, "bone"
	Singular	Dual	Collective
Nominative	osta	ostī	ostō
Vocative
Accusative
Genitive	stēs	steuš	ostō
Locative	stēi̯	steo	ostēi̯
Dative		stēma	ostē
Instrumental	stē

osta "bone" is from PEE *h₃esth₁ and behaves somewhat like a -h₁ stem somewhat similar to ponθōs. In the sing. nom. the accented syllable is in e-grade which, under the influence of the initial laryngeal, becomes Galic o-. In the oblique cases, the root is in zero grade, the suffix being accented, and surfaces as stē < *h₃steh₁-. In the du. gen. and dat., the laryngeal ending of the stem scans as part of the ending syllable beginning in vowel and thus does not lengthen the stem vowel, creating the stem of ste-; in the dat. the ending does begin with a consonant, which then causes the laryngeal to be part of the suffix syllable and lengthens it. The plural is a collective and shows e-grade in the root and vr̩ddhied o-grade in the nom. ending < *h₃estōh₁ "bones (of a skeleton)". The oblique stem of the collective is from *h₃esth₁-, the full-grade root having spread from the nom., replacing *h₃sth₁-. Gen. ostō reflects *h₃esth₁-os. The collective loc. has *h₃esteh₁ > ostē-.

m-stems

This class is known from only a few but important nouns, θéɣå "earth", žō "winter", and då "house". All m-stem nouns in Northian are feminine in gender, though with only a few examples, this may not be an actual rule in the proto-language.

	se θéɣå, "earth"
	Singular	Dual	Plural
Nominative	θéɣå	zémē	zémiš
Vocative	θéɣō
Accusative	zémā		zməṇġ
Genitive	gmō	gmōs	gmõ
Locative	zei̯me	gmō	gumho
Dative	gmē	gummō	gummuš
Instrumental	gūm

θéɣå is one of the rarer Northian words that reflects all three ablaut grades.

The behaviour of žõ "winter" is underlyingly similar to that of θéɣõ, but other phonetic changes have caused the surface forms to be altered in other ways.

ns-stems

mā̊ṇġ "moon" has one of the less transparent paradigms in Galic. In the received texts this word represents four morae, but the spelling does not reveal what the missing vowel. In view of the general development of PEE *-Hn̥s, most authorities write this word phonologically as måə̄ṇġ, standing for [māʔə̄ŋɡ̚]. It stands for PEE *mḗh₁n̥s > PNN *mḗuns > PN *māə̄ṇġ.

	sā mā̊ṇġ, "moon, month"
	Singular	Dual	Plural
Nominative	mā̊ṇġ	måə̄ṇhē	måə̄ṇhiš

Locative	mə̄ṇġ	mēṇhō	mēṇhsu
Dative	māi̯ṇhe	mēṇhmō	mēṇhmuš
Instrumental	mə̄ṇha

mn-stems

The mn-stems are prolific in Northian in both the Galic and Epic languages, and they exhibit three ablaut patterns. In this case, the oxytone pattern was normalized in masculine and feminine nouns, and the paroxytone in neuter nouns. The acrostatic ablaut pattern is restricted to a few inherited terms.

n-stems

There are also n-stems not as part of a suffix of *-mVn. As they are considerably rarer than the latter type, they are sometimes emphasized as "bare" n-stems. They are of two types, distinguished in the nom. sing., those with -ō and those with -ēn. Though uncommon, they are typical of family names in the Epic age.

In wei̯ō "wine", of the type ending in -ō, PNN stems are ablauting *wei̯-on- < *wei̯-Hon and *wī-n- < *wiH-n-. In the nom. sing. the root vowel is attracted by the final ō and becomes wei̯ō. In the oblique cases, stem *-n is altered before endings beginning in -m and becomes -ṇ.

	sā wei̯ō, "wine"
	Singular	Dual	Plural
Nominative	wei̯ō	wei̯onē	wei̯oniš

Locative	wīen	wīnō	wīṇhu
Dative	wīē	wīṇmō	wīṇmuš
Instrumental	wīn

ōrēn "lamb, ram" exemplifes the stems ending in -en-. The direct stem reflects PEE *wr̥h₁-en- > Galic ōr-en, by way of PNN *wurə-en, and the oblique *wr̥h₁-n- > PNN *wurə-n-. In both cases, PNN *wu dissimilates to *wo, and in Galic gives ō. This ablaut pattern contrasts with those in -on- in that the root is never accented and always shows zero-grade.

Locative	ōreine	ōrnō	ōrāṇhu
Dative	ōrnē	ōrāṇmō	ōrāṇmuš
Instrumental	ōrnē

r-stems

R-stem nouns contain members from all three accentual patterns. mātə̄ "mother" represents the group with PPX accent, which persists on the root syllable and always takes suffix and ending in zero-grade.  vrātə̄ "brother" is declined in the same manner. This is a small group of nouns recognized by their unaccented endings in -ə̄.

	sā mātə̄, "mother"
	Singular	Dual	Plural
Nominative	mātə̄	mātūr	māθriš
Vocative
Accusative	māθrum		mātə̄rəṇġ
Genitive	mātūš	māturuš	māθrõ
Locative	māθre	māturo	mātuššu
Dative		māturma	māturmuš
Instrumental	māθra

Gen. mātūš < PNN *māturs < PEE *meh₂tr̥s, while māetūr is from the Epic language, which has restored the *r that has been dropped in *-rs. Dat. māθre < PEE *meh₂tri, with the (possibly) innovated zero-grade ending, contra full-grade ending *-ei̯. In the du. the stem ending in resonant causes final *-ə to drop and lengthen the preceding *u. The acc. pl. seems to reflect PEE *meh₂tr̥n̥s, which is irregular, but the other Nordic languages point to *meh₂tern̥s (with full-grade in the suffix), and neither form is particularly informative as both are in unison with respective nom. pl. stems. The Nordic form is assumed to be the original, with Northian one having undergone some assimilation not seen elsewhere.

In Galic, mātūr "two mothers" is often an ellipsis for "mother and father".

sóhitə̄ "daughter" represents the oxytone group of the r-stems, which includes many agentive nouns that terminate in -er and -or. They are recognizable by their zero-grade nom. endings and full-grade -ō endings in gen. The behaviour of the word ɣehə̄ < PEE *ǵʰésr̥ "arm" is underlyingly identical. In the nom. sing. the strong stem reflects PNN *dʰwegə- < PEE *dʰwegh₁-; the weak stem from PNN *dʰugə- The initial *dʰwe > Galic sō-. The weak stem should expect to surface as *θuɣaθr-, but the initial aspirate is simply de-aspirated probably in avoidance of three consecutive fricatives to give attested *duɣaθr-, to which regular OX endings are appended.

Locative	duɣaθrē	duɣaturō	duɣatuššu
Dative		duɣaturmō	duɣaturmō
Instrumental	duɣaθrē

patå "father" is at a small variance from the pattern of "daughter", where in the nom. the accent is on the ending instead of the stem; otherwise, it follows the pattern of "daughter" nearly exactly. Only the gen. form paθrūš is aberrant and is influenced by "mother"; this genitive ending is common to all two-syllable nouns ending in -r, with the exception of "hand". patå reflects PNN *patēr, with resonants regularly lost after long vowels in final position, possibly becoming *patēə then > patå /patā.a/.

The paroxytone declension of āštə̄ "star" has a unique blend of formations expected from PPX and PX patterns. The nom. sing. āštə̄ reflects PEE *h₂eh₁str̥, a form not seen elsewhere in Erani-Eracuran. Gen. strūš could mechanical restore to PEE *h₂h₁str̥s, but the zero-grade forms are, in all likelihood, from "mother" or "brother" and have displaced the expected PX form *h₂h₁sters, in a way contrary but not unparalleled in the general analogical preferences of Northian.

An r-stem noun not within the formation -tr is nēr "man", gen. drō < PNN *nros. As it is seen this noun originally has hysterokinetic accent, but acc. sing. drum and pl. drə̄ reflect PEE zero-grade stem *nr-. Nom. pl. neriš is the only place where the full-grade stem appears in the paradigm.

l-stems

The l-stems originally inflect as other ablauting consonant stems, but because intervocalic *-l- regularly > -y-, the resulting paradigm presents certain quirks not seen in the normal consonant-stem paradigm.

s-stems

The noun au̯šōs "dawn" is an OX animate noun. The noun has three basic stems: the strong stem which appears in the sing. nom. and voc. comes from PEE *h₂eu̯s-os-, with regular lengthening of the final syllable anticipating a zero nominative ending; the middle stem appears in the other direct cases and is from *h₂us-es-; the weak stem appears in all other cases and is from *h₂us-s-, with full-grade endings as expected in oxytone words.

os/es-stems

The os/es-stems are a class of very common neuter nouns in Northian and are directly cognate to those found in Nordic languages. Together they have both PX and PPX patterns. Though in Galic times and later only the PX pattern is productive, there are four or five very common PPX os/es-stem nouns constituting a nearly-complete paradigm.

In PX the nom. sing. ended in -ō, which is a regular reflex of PNN and PEE *-os; this *-os is not to be confused for the thematic nom. ending or the athematic OX gen. ending and instead is a bare stem. The gen. ended in -eh-ō < PNN and PEE *-es-os, intervocalic *s before back vowel regularly > h, possibly by retraction. In the dat. intervocalic *s > z before front and central vowel, as is the case in the du. and pl. nom. Before endings beginning with consonant, s is preserved or altered in regular ways.

The PPX version of this stem had a few differences to the PX version that enabled it to withstand the general tendency to substitute PPX with PX or OX forms; its preservation cannot be unlinked with the prevalence and prominence of the noun menō "mind", a central idea in the Galic religion and often mentioned in the Gales. The nom. sing. was menō < PEE *men-os, with ending -ō undergoing the same changes as the PX counterpart. The gen. had mēṇġ < PNN and PEE *men-s-s. In dat. meṇhi < PEE *men-s-i the preservation of final *-i is irregular.

i-stems

The i-stems were a prolific class of nouns in Northian during the Galic period. In PEE, the i-stems were completely parallel to the u-stems in virtually all contexts, but due to sound changes their surface forms in Northian are quite different. Accordingly, they are considered separate classes in Northian tradition.

u-stems

The plain u-stems of Northian reflect three ablaut patterns, and excepting the acrostatic they are both attested abundantly in the Galic language. The acrostatic pattern provides only inherited nouns, with no sign that new terms with this pattern were made.

Dative	gunōi̯	gunumō	gunumuš	daunōi̯	daunumō	daunumuš
Instrumental	gunū			daunnū

The OX pattern had a nom. sg. ending in PNN *-ou̯-s which regularly gave Galic -ō-š, the final -š being a regularly conditioned result of *-is and *-us. The gen. and dat. reflects PNN *-u-os and *-u-ei̯ as expected in a hysterokinetic pattern. The loc. shows full-grade in the stem reflecting PNN *-eu̯-i > *ei̯-u̯e > Galic -ei̯-ō. The ins. may reflect PEE *gen-u-eh₁ or *gen-u-h₁, and the metre does not clarify. The dual behaves as expected. In the plural, final -eōs < *-eu̯-es, as though *-e-u̯es. The expected *-eu̯-iš anomalously does not occur with OX nouns but does with PX nouns, which may be a dialectal influence. The acc. shows -eõ which is from *-eu̯-ōn < *-eu̯-ons < *-eu̯-uns.

In contrast with common-gender u-stem OX nouns, neuter u-stem OX nouns are very rare, and only one item dāno "dew, tear" is well-attested. The nom. sing. is from PEE *déh₂nu > PNN *dānu. The oblique stem is from PEE *dh₂n̥-u- > Galic daunn- because *-nu̯- is subject to assimilation to -nn-. The dual has *dāun-w- (effectively a mixture between direct and oblique stems) because the neuter dual ending is vocalic and causes the preceding *-w- to become a consonant, which then causes the *-n- preceding it to become *-n̥-. Interestingly, a person's tears is usually inflected as a dual, possibly itemizing tears as "streams of tears" coming from a person's eyes (which is by default inflected as dual).

The PX pattern in u-stem nouns is very prolific in both the Galic and Epic languages. Many are abstract nouns with the ending -tuš. The nom. ended in -uš, but it is not uncommon in the Late Canon material to see -ō. While many nouns would show root ablaut, the example provided above does not and therefore has all components in zero grade in the nom; the hypothetical forms *seu̯i̯uš or *sou̯i̯uš would be expected based on the general ablaut tendencies, but it is in fact the proto-form of sui̯uš that is attested in all EE languages. The gen. ended in *-ou̯-s, whence -ō-š. All the other oblique cases show -eu̯- in the suffix, which does very early spread to the gen. as well, such that -eu̯-s actually outnumbers the older -ou̯-s by a factor of more than 40 to 1.

The ins. sing. and nom. du. have identical endings becuase their PEE forms were both *eu̯-h₁ > Galic -ēu̯. The gen. du. has -eu̯ō, which reflects *eu̯-us; here, the final *-us dissimilated from the preceding vowel and became *-os, which regularly > -ō. The loc. has -eu̯-a which is the reflex of *-eu̯-o dissimiliated from *-eu̯-u. The nom. pl. and acc. have the expected forms, with PNN *-uns > Galic -ə̄ṇġ. All other forms in the plural are straightforward.

The neuter version of the PX u-stems displays regular ablaut, which alternates strong and weak stems. The strong has o-grade from PEE *poh₂-i̯u > PNN *pōi̯u > Galic pōi̯o. The oblique stem is from PEE *ph₂-i̯ou̯-s > PNN *pə-i̯ou̯-s > Galic pii̯ōš, where PNN *ə regularly becomes Galic -i- before high vowels or their allophones. The du. and pl. nom. have the same form because their endings in PEE were *-h₁ and *-h₂ respectively, which were levelled and trigger Cammer's law lengthening the preceding vowel.

xͮōn

xͮōn "woman" continues the PEE proterodynamic declension ending in *-h₂. This suffix also underlies the ī- and ū-stem declensions in Northian but is otherwise rarely seen alone. The full-grade stem is from *gʷénh₂-, and the zero-grade *gʷnéh₂-.

Instrumental	gnaθri̯ē

ū-stems

The ū-stems were exactly parallel to the ī-stems at the PEE and PNN levels, but due to phonetic changes have become nearly unrecognizable. The nom. sing. of hysterokinetic stems had accented root syllable and an ending in PEE *-uh₂-s > *PNN *-ūs > Galic *-ūš. The acc. would have ended in PEE *-u̯eh₂-m̥ > PNN *-wē-um. In Galic, *-wē- regularly > -i̯ō-, as also in loc. In the oblique cases, the stem ended in -ū-, to which full-grade endings were added. The zero-grade stem has replaced the original full-grade one in the dual nom. such that it projects the (implausible) PEE form *tn̥-uh₂-h₁. The metrically trimoraic -ū ending represents final *-ūᵊ, as otherwise it would have become *-ō.

r/n-stems

The r/n-stems, or heteroclitics, continue a class of (mostly agreed to be) archaic EE nouns that had different suffixes depending on case even at the level of the proto-language. They are special in that they are all neuter nouns with fundamental meanings and show acrostatic > PPX or proterokinetic > PX ablaut in the singular and dual. These nouns do not take plural endings in Galic times but rather form a "collective" which take OX singular endings. In this respect they are similar to mn-stems and dissimilar to es/os-stems, which are both reserved to neuter nouns. In the Epic language, many heteroclitics also formed ordinary plurals from the zero-grade stem, which agree with singular verbs and have meanings different to their collective brethren.

In the Galic language, many heteroclitic nouns have opaque forms owing to their (generally) short stem and susceptibility to ablaut, vocalization, and internal sandhi. From a historical angle, there are three heteroclitic stems that give rise to differing forms in Northian—those in *-wr̥/wn-, *-Hr̥/Hn-, and *-rr̥/rn-. The type of på "dwelling" ended in PEE *-r-r̥ in the nominative, but the second *r is syncopated into the first in its evolution to Northian; the oblique stem assimilates to -nn-. The type with nom. ending in -ō such as perå "mountain" ended in *-wr̥ in the proto-language. This ending would first become PNN *-wur, then Northian *-wor; in Galic, *-wo- following a vowel regularly becomes -å. For the stems ending in laryngeal, the effect is most noticeable before the PX ending *-ens; this ending surfaces as -āš after *h₂- and -ōḥ after *h₃-.

PP i̯å "year", is from *yoh₁-r̥ > *yō-ur, gen. *yeh₁-n̥-s > *yē-uns. In Galic, unaccented final -ur regularly drops and lengthens preceding syllable. The strong stem with *-r- is visible in the dual nom. In the gen., *uns > *ə̄ṇġ. In the dat. the long vowel resists mutation caused by final short *-i. The ins. ending has dropped, but the preceding long vowel cannot be further lengthened to *å because it is closed. The rest of the du. behaves as expected. In the collective, the stems are from the e-grade and zero grade (as opposed to o-grade and e-grade of the PPX singular and dual). The nom. has a vṛddhied ending. The zero-grade stem is from *ih₁-n- > Galic īn-, and OX endings follow as usual.

i̯å is famously found in G.Nr. 59/2, contemplating the relationship between a single revolution of the annual cycle and the cycle of annual cycles, i̯ā̊ toi̯ i̯ə̄ṇġ, īnō i̯å "years of that year, that year of years!"

pāu̯or "fire" represents the heteroclitic nouns with proterokinetic pattern, with accented stem in the oblique cases. The PNN form is *pāwur and gen. *pəwens, from PEE *peh₂-wr̥ and gen. *ph₂wen-s. In the nom., the sequence *-wu- differentiates to *-wo- prehistorically. In the gen. *ə before -e- regularly becomes -a-. Final *-s drops and causes the preceding *-e- to lengthen. Mutation occurs in the dat. with *-e- > -ei̯-.

Other common heteroclitic nouns include:

• PX aɣə̄ ɣēn "day"
• PX petə̄ ptå "feather"
• PPX ōθə̄ ōθə̄ṇġ "water"
• PPX perō perō "mountain"
• PPX på perə̄ṇġ "house"

l/n-stems

sā̊l, phonologically probably sāōl, "the Sun" continues the PEE heteroclitic stem in *-l/n-. The strong stem descends from PEE *seh₂w- > sāw-; the weak stem from *sh₂ew- > saw-. The nominative is due to the regular sound change of *wu > wo. Genitive has hu̯ə̄ṇġ, for expected *hwēn < *swens < *sh₂wens; this possibly suggests the proterokinetic ending *-ens was replaced by acrostatic ending *-n̥s prehistorically, as from from PNN *swuns < PEE *sh₂wn̥s. However, because other Nordic languages show a reflex of *sh₂wens, the insertion of the acrostatic ending must have occurred only after Northian diverged from PNN.

The word sā̊l signifies a heavenly body that is considered a god in early Northian religion and is usually found in the singular in the Galic language. There in in the dual, "the two Suns" is an ellipsis for "the Sun and the Moon". After the Late Canon period, the genitive dual sunuš < PEE **sh₂wn-us displaced the singular hu̯ə̄ṇġ in all but ritualistic contexts as the normal word for "Sun's". During the imperial period, the stem from the dual was re-interpreted as an o-stem and formed the neologism sunō for the nom. sing., which also replaced sā̊l in non-ritualistic contexts.

nt-stems

The nt-stems are very closely associated with the formation of the present active participle in -nt-. But while participles have distinct masculine, feminine, and neuter forms, nt-stem nouns have the form of masculine participles and lexical gender. With nouns in -m, nt-stems often have three ablaut grades.

Acrean words

Many words in Northian are Old Nordic loanwords from speakers of Acrean, which was used as a lingua franca in western Eracura for centuries under the influence of the Acrean Empire. These words were so numerouš that many were not nativized and were declined according to an approximation of the thematic declension in Old Nordic. For the most part, these endings are exact cognates with the thematic ones in Northian, but because of intervening sound changes, they are taught separately. Where there was a distinct vocative, the nominative form has displaced it. There are also no dual forms for these nouns, for which neologisms have sometimes been suggested, to no general acceptance. Since Old Nordic had no locative case, this form is always identical to the dative where Northian syntax demands the locative.

Irregular nouns

Country names

All country-names in Northian are feminine in gender, though the declensions may not reflect this readily. Nevertheless they agree with feminine adjectives and participles in all cases.

"Æþurheim", the name of the country to the southwest of Shalum, has an invariant stem with full grade throughout and initial persistent accent in Aí̯θrō-, which takes oxytone endings. The vocative form is identical to the nominative, showing full grade. Because the accent is in its expected position in the nom. and voc. forms, the acute accent on the i is not necessary there, while it is found in all other forms to denote the irregular accent.

"Shalum" behaves in a manner more reminiscent of a regular n-stem noun in oxytone and has the expected endings and accentual positions, but the stem does not display apophony as is usual in this class of nouns.

"Acrea" is named Aṇhrōs, which is a compound from aṇh- "lord" and rōs "realm, power", gen. Aṇhurō.

Adjectives

Adjectives agree with the nouns they modify in gender, number, and case, within their lexical paradigms. Inasmuch as nouns have differing endings that convey the same number and case, so too do adjectives have lexical paradigms; adjectives do not agree with the paradigms of nouns that they modify.

woḏs-stems

From PEE *bʰebʰidʰ-wṓs, forms perfect active participles from the zero-grade perfect root. The exact proto-form of the perfect active participle in Northian has long been an unresolved issue, as the final *-s of the stem does not undergo rhotacism as expected in other words. This has led to be postulation that the pre-form was actually *-wos-s or *-wōs-s, with a restored final *-s. The first *s then changed into a consonant of unknown value usually written *ḏ, which then disappeared in all forms except in the neuter nominative singular, where it surfaces as an anomalous -ḫ.
