ornitho- (English)

Where does "ornitho-" come from?

The English prefix 'ornitho-' meaning 'of or pertaining to birds' descends from Ancient Greek 'ὄρνιθ-' ('órnith-'), which is the stem of 'ὄρνις' ('órnis', meaning 'bird')[1]. This Greek root traces further back to Proto-Hellenic and ultimately derives from the Proto-Indo-European root '*h₃érō'[2].
