-twa (Polish)
Where does "-twa" come from?
The Polish suffix '-twa', which is used to form abstract nouns or nouns of place[1], has a deep lineage inherited from Proto-Slavic '*-tva'[1]. This Slavic suffix traces further back through ancient roots to the Proto-Indo-European sequences '*-tweh₂', '*-eh₂', '*-h₂', and '*-tus'[1]. Related forms also appear in other Slavic languages, such as the Czech suffix '-tva'[1].
