Etymology[edit]

From Latin aphaeresis, from Ancient Greek ἀφαίρεσις (aphairesis, a taking away), from ἀφαιρέειν (aphaireein) (from ἀφ- (aph-) (aph-, “aph-”, variant of ἀπό (apo, off”, “away from) before an aspirated vowel) + αἱρέειν (aireein, to take”, “to snatch)) + -σις (-sis) (-sis, suffix forming nouns of action); the grammatical sense developed in Latin.[1]
