Trellinese is an Ethlorek language of the Mede-Lorecian language family. It is spoken as a first language by the majority of Trellinese people and as a second language by significant populations in the non-Ethlorek populations in the rest of the Trellinese Empire, particularly in the Isles of Velar. It is an official language throughout the empire, and enjoys constitutional protection as an official second language in Cadenza.
Originally from the Astyrian continent of Lorecia, Trellinese travelled with the Ethlorek migrations to Trellin, where it displaced the Velaric languages spoken south of the river Serëtanz. It became the dominant language in the dominions of the Trellinese Empire and the neighbouring Ethlorek state of Arimathea, and largely influenced the decline of the Ahéri language outside of its traditional bastions in Hysera and Jajich.
The development of Trellinese has been artificially restrained several times in its history, with the result that the language bears strong resemblance to, and would likely be mutually intelligible with, Old Trellinese. The language reforms of Ri'erha II, in 1050, saw the introduction of the Latin script in administration. A grammar book of the early ninth century was used as the basis for this writing reform.
