Baen is the language of the Bae, a group of social humanoids living on Aeniith. Baen exists in five main dialects. This grammar sketch is for Baenfrinna (or simply Baen, as it is called often), which is the most widely spoken amongst the Bae (many Bae may know two or more dialects, usually including Baenfrinna) and the best known amongst outsiders.

Baen is a highly agglutinative language, meaning it compiles many morphemes into single words. It also has a declension system of nine cases, five tenses, five aspects, three voices, and three modes. It is also unusual in that it uses both case markers and adpositions.

Baen has a nominative/accusative verbal system, which means that it treats subjects of intransitive verbs and agents of transitive verbs similarly. It also displays syntactical nominative/accusative features.

It has a fair-sized phonemic inventory consisting of twenty-three consonants and five vowels, making for a total of twenty-eight phonemes. Baen is “consonant-centric” and has many different acceptable consonant clusters.
