Sileo

An easy-going name reflecting tranquillity, stillness and silence, Sileo comes from the Latin sileō meaning "to be quiet" or "to rest". Despite this calming meaning, the name has plenty of energy in its sounds and flow, and could be an interesting route to nickname Leo.

Some sources suggest the name is also a Spanish and Italian variation of the Greek Syleus, a name meaning "privateer" or "right to seize a ship".

Pronounced SIL-ee-o.
