History
Etymology
From Late Middle English acute (“of a disease or fever: starting suddenly and lasting for a short time; of a humour: irritating, sharp”), from Latin acūta, from acūtus (“sharp, sharpened”), perfect passive participle of acuō (“to make pointed, sharpen, whet”), from acus (“needle, pin”). The word is cognate to ague (“acute, intermittent fever”). As regards the noun, which is derived from the verb, compare Middle English acūte (“severe but short-lived fever; of blood: corrosiveness, sharpness; musical note of high pitch”).
