Today's Word "acuity"

Acuteness of perception on

Published in Vocabulary

acuity \uh-KYOO-uh-tee\ (noun) - Acuteness of perception or vision; sharpness.

"Horses tend to shy a lot because the construction of their eyes is optimized for a near 360-degree field of view, useful for spotting danger, but the price the horse pays for that is relatively poor acuity and some out-of-focus spots that can cause objects within the field of view to suddenly sail into sharp focus." -- Stephen Budiansky, 'If a Lion Could Talk'

 

Acuity comes from Latin acutus, "sharpened, pointed, acute," past participle of acuere, "to sharpen."
