acrasia

Etymology

Learned borrowing from Late Latin acrasia (“lack of temperance”), and from its etymon Ancient Greek ᾰ̓κρᾱσῐ́ᾱ (ăkrāsĭ́ā, “bad mixture”), from ἄκρᾱτος (ákrātos, “pure, unmixed; of a person: intemperate, violent”) + -ῐ́ᾱ (-ĭ́ā, suffix forming feminine abstract nouns). Ἄκρᾱτος (Ákrātos) is derived from ᾰ̓- (ă-, prefix forming terms having a sense opposite to the stems or words to which it is attached) + κεράννυμι (keránnumi, “to blend, mix; to cool or temper by mixing”) (ultimately from Proto-Indo-European *ḱerh₂- (“head, top; horn”)) + -τος (-tos, suffix forming adjectives). Doublet of acrasy.
