Usage notes

 * 1) If the suffix comes to a word ending in a consonant, it takes  (or *-ï) form.
 * However, Oghur languages only use -i instead of -si after vowels, by deleting the last vowel and adding the suffix ( → Proto-Oghur *in e -i → 🇨🇬 "his/her cow", from ).
 * 1) This word has a feature where there is an "unstable n" that occurs only when it is conjugated, so the form becomes *-sI(n-).
