Definition acute

Etymology

From Late Middle English ac?te (“of a disease or fever: starting suddenly and lasting for a short time; of a humour: irritating, sharp”), from Latin ac?ta, from ac?tus (“sharp, sharpened”), perfect passive participle of acu? (“to make pointed, sharpen, whet”), from acus (“needle, pin”), from Proto-Indo-European *h?e?- (“sharp”). The word is cognate to ague (“acute, intermittent fever”).

As regards the noun, which is derived from the verb, compare Middle English ac?te (“severe but short-lived fever; of blood: corrosiveness, sharpness; musical note of high pitch”).
