Meaning of Leo

Root meaning "lion"

Leo is the Latin word for 'lion' and was widely used in the Roman Empire as both a personal name and a title of strength. It was borne by thirteen popes (Leo I, 'the Great', being the most influential) and has been in continuous European use since Late Antiquity. Leo's modern popularity in the English-speaking world is partly driven by parents wanting a short, strong name and partly by the trend toward classical one-syllable boys' names.
