MeaningThe English word sly, meaning 'cunning, crafty' — a plain fact families should weigh. It is also a well-known short form of Sylvester, carried by musician Sly Stone and by the actor Sylvester 'Sly' Stallone.
Sly as a first name comes chiefly from Sylvester, shortened. The word itself means 'crafty' or 'cunning', which is worth naming outright rather than smoothing over. Its cultural warmth comes largely from Sly Stone and Sly Stallone (said 'SLY').
It is very rare as a given name in the U.S. Rare, punchy, and one syllable.
Did you know? Sly does double duty — it is the everyday English word for 'cunning', and a nickname for Sylvester, worn by musician Sly Stone and actor Sylvester Stallone. We state both plainly so families choose with open eyes (said 'SLY').
