Usage notes
Unlike many suffixes, this suffix always lack vowel harmony, due to its history as an enclitic. This plural suffix also causes fusion with case endings:
Nominative cv -сем Accusative-dative cv -сене Genitive cv -сен, cv -сенӗн Instrumental cv -семпе Locative cv -сенче Ablative cv -сенчен Abessive cv -сенсӗр Causative cv -сеншӗн
Among the fused suffixed above, only the instrumental form that never fuses with this plural suffix's last consonant.
