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