Reconstruction:Proto-Slavic/-yni

Etymology
Resultant from the fossilization of the feminine agentive suffix to v-stem. In rare cases, the original v-stem noun has survived, e.g. →.

Nominative singular (with a hard consonant), genitive  (with a soft consonant) reflects  proterokinetic, , and is a cognate inflectional class as found in Sanskrit  (genitive ), Ancient Greek  (genitive ), Gothic  (genitive ) and Lithuanian  (genitive ).

Already during the Balto-Slavic period these nouns almost completely merged with jā-stems, but kept the separate nominative singular ending. In Late Common Slavic this was leveled out, and already in Old Church Slavonic nominative singular is attested spelled with the soft consonant, following the rest of the paradigm.
