Having the most acute point or edge; most clever or intelligent; most intense or severe.
From Old English 'scearp' meaning cutting or keen. The word has maintained this meaning for over 1,000 years, with uses extending from physical sharpness to mental quickness to emotional intensity.
Remarkably, 'sharp' works as both a physical and mental descriptor in English—something sharp cuts, a sharp mind cuts through confusion, sharp pain cuts through comfort—all from the same root about cutting ability.
