The Brythonic (Brythonec) Language is a language, derived from Welsh, Breton, Scottish, Irish, and English, that was the official language of Great Brython until its eventual collapse. The language is still semi-official at local levels throughout the post-Brythonic Alban Isles, and is official in De Mor Tir. The language was created in 1763 by the Brythonic Lingusitic, Heraldic, and Vexillogical Society (BLHVS) in response to the need of a common language between all of Great Brython.
