Camila comes from the Latin camillus, meaning a young attendant who assisted Roman priests at religious ceremonies — specifically a noble-born child who helped with sacrifices and rites. The name is associated with Camilla, queen of the Volsci, a warrior maiden in Virgil's Aeneid who could run across a field of grain without bending the stalks.
Camila is the standard Spanish and Portuguese form, while Camilla is the English. The Spanish form has surged in the United States in the 2010s, in part through the singer Camila Cabello, who was born in Cuba and raised in Miami. Today Camila sits in the U.S.
Camila does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Camila reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
