What Does the Name Sly Mean?
Sly is an English name that comes from the English word sly, meaning "cunning," "crafty," or, in older use, "skillful." The word descends from Old Norse slœgr ("sly, cunning, clever"), which entered Middle English as sly or sleigh. In its earliest recorded sense the word meant "clever, skillful, dexterous," and it later shifted toward the modern meaning of "crafty" or "deceitful."
As a personal name, Sly is also commonly understood as a short form of Sylvester, which comes from Latin silvestris, "of the woods" or "wooded," from silva, "forest." This is a separate line of origin: the word meaning and the shortening of Sylvester are not the same derivation, and the name can be explained by either.
Sly Name History & Origins
Both the surname and the occasional first name Sly are English. The surname is a nickname surname taken from the word sly, given to someone regarded as clever or crafty, and it is found in English records from the medieval period onward.
As a first name, Sly is uncommon and is used mainly as a nickname. The actor Sylvester Stallone is widely known as Sly, an informal shortening of his given name. Sylvester itself was established in English use through the medieval church, since Saint Sylvester was a fourth-century pope, and dropping the final element of a longer name to form a short form is a familiar English pattern. The musician Sylvester Stewart performed as Sly Stone and led the band Sly and the Family Stone, which helped keep the short form in public view.
