Proto Csillan

General information
Proto-Va'aini is the first spoken language in the western continent of Nirunei, Andar.

Variations
Being a Proto-Language, most of the phonology is reconstructed from its descendents. Many linguists argue that the interdental series may have been alveolar, given that t softens to an s next to other plosives in southern languages, but northern languages soften t to θ between vowels, leading most to believe that alveolar variants of the interdental series were free variants that became dialectal between north and south.

Vowels have many other proposed variations, but the only ones of note is y being ɪ and ù becoming ʌ, though this is usually accepted as a sound change for northern dialects.

Phonotactics
Words can begin with any consonant or any fricative or plosive + t, and can be followed by r. C(r)V or [p, b, ć, f, v, s]t(r)V The next syllable can begin with n, r, or l plus any fricative or plosive and can again be followed by r. It can also be any fricative plus any plosive, other fricative, n, l, or r. [n, r, l][p, b, t, ć, f, v, s](r)V, [f, v, s][p, b, t, ć, f, v, s, n, r, l]V, C(r)V. Another syllable with one of these structures is allowed, but the final syllable can end with any vowel or consonant except plosives.
