Origin: Latin

Meaning: Wooded, forest; Skillful expert; Crafty guileful underhand

Who knew there was a cunning nickname for Sylvester! Short, sweet, and a bit cheeky, Sly is a boy's name destined for a one-of-a-kind munchkin. This rare pick is rooted in the Latin word silva, meaning "wooded" or "forest," adding to its air of mystery and intrigue. It also has Old Norse roots to slœgr, referring to a "skillful expert" and also "crafty guileful underhand." A little disclaimer for the wise—if you choose Sly, you may want to keep an eye on your cookie jar. Plus, you can introduce baby to the Looney Tunes' Sylvester the cat and have good reason to adopt the exclamation sufferin' succotash. If that doesn't convince you, there's always Rocky actor Sylvester Stallone.
