Leo is the Latin word for lion, used as a name for its direct associations with courage and boldness rather than any hidden meaning. It's a name that wears its symbolism plainly -- strength on the surface, not something to be uncovered through etymology.
When you are loathed use Venus who has very strong influx and quick response in this and other aspects, and means renovation and growth. - Picatrix (Andalusia, ~1000.AD)
