-ία (Ancient Greek)
Where does "-ία" come from?
The Ancient Greek suffix '-ία' is used to form feminine abstract nouns from adjective stems, and rarely from verb or noun stems[1]. This suffix descends from the Proto-Indo-European form '*-i-eh₂'[1]. Similar forms appear across other language branches, including the Latin suffix '-ia' and the Proto-Slavic suffix '*-ьja'[1].
