Proto-Teskwan is the language of the Teskwan peoples of Central Borea. It is agglutinating and a SOV language with tripartite morphosyntax.

Teskwan phonotactics require closed syllables for all roots, and very occasionally closes syllables for morphological prefixes and suffixes. The syllable nucleus can contain all vowels including /ə/.

S = stops, F = fricatives, A = approximants, N = nasals

Basic phonotactics are as follows:

Onset: S(F/A), F(S/A/N), N(A), or A Coda: A(N/S), F(S), N, or S

/j w/ are not allowed in the coda, /w/ rounds the previous consonant and disappears.

Labialized consonants labialize the preceeding or following consonants, leading to some complex allophony.


Due to the consonant cluster labialization rule, a set a allophones must be described seperately from the base phonology.

Certain consonants can be rounded, and others are mutated due to phonological rules. Consonants which phonologically take roundedness can surface as rounded due to mutation.

For example, */nʷatʷnas/ is not a permissible word, as the /n/ must take labialization due to the preceeding consonant, therefore /nʷatʷnʷas/. In other cases, the consonant goes through mutation. */nʷatʷɾəs/, which is not permissible, becomes */nʷatʷɾʷəs/ but due to phonological mutation, it becomes /nʷatʷʁʷəs/.

Consonant Mutations
Plain b̥ʷ pʷʰ ɾʷ
Lenition b̥͡β̥ʷ p͡ɸʷ ɸʷ ɫʷ ʁʷ ɥ

Note that the first two mutations are lenition but the following are mixed mutations. The term "lenition" is used loosely to include all of the mutations.
