Aithar

Aithar (Northian: Ái̯θar) is a deity of the Northian pantheon with elemental association with the sky and light, and characteristically is considered a god of priesthoods and of sacrifices.

Etymology

Ái̯θar is from Proto-Erani-Eracuran *h₂eydʰ-r̥ and has proparoxytone accent in the genitive Ái̯θūš. This suffixed word is not attested outside of Northian, and so some authorities believe it is an innovation internal to the branch. Given its proparoxytone genitive, which is generally not made after the Galic age, the word itself must be old, though its first attestation is in sub-Galic material. Additionally, the root also gives a related neuter stem, used as a common noun, with the genitive ái̯θaṇġ < PNN *ái̯θunh.
