Ways to Be Acute

For such a short and simple-looking word, acute has a rather bewildering range of meanings. It first entered the English language with a medical sense, referring to the sharpness or severity of a symptom. It retains this meaning today, but can also refer to the severity of more general matters, such as "acute embarrassment" or "an acute shortage."

Acute is also frequently used to describe less troublesome matters, such as keenness of perception ("an acute observer" or "an acute sense of smell"), a type of angle (one measuring less than 90 degrees), or the demand for urgent attention ("acute danger").

Word History

Etymology

Middle English, borrowed from Latin acūtus "sharpened, pointed, having a violent onset, discerning, less than 90 degrees (of an angle)," from past participle of acuere "to sharpen, rouse, stimulate," probably derived from an otherwise unattested adjective stem acū- "sharp"; akin to acū-, acus "needle," a perhaps independently derived noun; further akin to Old Church Slavic osŭtŭ "thistle," Lithuanian ãšutas "hair of a horse's tail or mane"; all going back to the Indo-European base *h2eḱ- "sharp" — more at edge entry 1
