bio- (English)
Where does "bio-" come from?
The English prefix 'bio-' traces its lineage back to Ancient Greek 'βιο-'[1], which serves as the combining form and stem of 'βίος' meaning 'life'[1]. This Ancient Greek term likely derives from the Proto-Hellenic form '*gʷīwos' or '*gʷih₃wós' meaning 'alive'[2]. Further back in time, all these forms ultimately connect to the Proto-Indo-European root '*gʷeyh₃-' meaning 'to live'[2].
