Meaning & Origin

nominative singular of Deu; alternative form of Deus

Dex is a boy's baby name of Latin origin, a short form of Dexter, from the Latin dexter, meaning 'right-handed' or 'skillful, fortunate' — the right hand was historically associated with skill and good fortune.

Compact and punchy, Dex has the one-syllable cool of names like Rex, Jax, and Knox. The television serial killer Dexter Morgan from Showtime's Dexter gave the name a complicated but memorable cultural presence, while the simple meaning of skillfulness makes it genuinely aspirational for any child.
