Etymology

It is borrowed from Latin acūtus (“sharp-pointed”),[2][3][4] the past participle of acuere, to sharpen,[2][3][4] related to acus, needle,[2][5] from a root meaning “sharp” (see acid and edge).[3][4][2] The acute accent translates Ancient Greek ὀξεῖα (oxeîa), sharp.[4]

Earliest recorded meaning

Of a disease, brief and severe, coming quickly to a crisis, as opposed to chronic: before 1398, in Trevisa's translation of Bartholomew.[2][3]

Semantic evolution

After the Middle English period acute developed figurative and other meanings:[2] sharp-pointed (by 1570, with the acute angle),[2][6] penetrating or sharp-witted (by 1588, in Love's Labour's Lost),[2][3] and of sounds shrill or high (1609).[6] Of feelings or pain, intense, is from 1727, in Swift.[2][3] The acute accent is from about 1600 as a noun,[3] and an acute ward, for patients needing short-term treatment, from 1958.[6]
