Nominative singular *-yni (with a hard consonant), genitive *-ynję (with a soft consonant) reflects Proto-Indo-European proterokinetic *ʹ-ih₂, *-yéh₂-s, and is a cognate inflectional class as found in Sanskrit देवी (devī́, “goddess”) (genitive देव्या (devyāḥ)), Ancient Greek Μοῦσα (Moûsa, “Muse”) (genitive Μούσης (Moúsēs)), Gothic 𐌼𐌰𐍅𐌹 (mawi, “girl”) (genitive 𐌼𐌰𐌿𐌾𐍉𐍃 (maujōs)) and Lithuanian martì (“daughter in law”) (genitive marčiõs).
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.

** The second form occurs in languages that contract early across /j/ (e.g. Czech), while the first form occurs in languages that do not (e.g. Russian).
