Things to Know About This Name
- Associated with Lex Luthor, Superman's supervillain nemesis — some parents may want to be aware of this connotation
The Story of Lex
Lex is a short form of Alexander (and related names like Alexis and Alexandra), which comes from the ancient Greek 'Alexandros' — a compound of 'alexein' (to defend) and 'anēr/andros' (man), meaning 'defender of men.' Alexander the Great (356–323 BCE) made this name famous across three continents, and its short forms (Alex, Lex, Alec, Xander) have flourished ever since. Lex stands out among these for its punchy, one-syllable strength.
Lex has risen as a standalone name in the 2010s as parents embraced short, strong boy names (Max, Rex, Jax, Dax). While Alex remains far more common, Lex appeals to those who want the Alexander heritage in its most concentrated form. The name got a fictional villain boost from Lex Luthor in the Superman universe.
Alexander — from which Lex derives — is one of the most historically significant names ever borne, carried by one of the greatest military commanders in history. Three popes, countless kings, and heroes across cultures have borne this name. Lex distills that heritage to its essential core.
