Meaning & origin
Demoni is a modern name that first entered U.S. birth records in 1997, initially given about once per 100,000 newborns. Its popularity grew through the 2010s, reaching a peak rank of 5,399 in 2021. Since then, the name has been on a falling trajectory, declining in use through 2025. The name appears to be an invented coinage, likely influenced by the French name Demi or by the sound of names like Damon with a fashionable ending. It has not been recorded as a top state name in any state, suggesting it remains a rare and niche choice across the country. Demoni is used for both boys and girls, reflecting a broader trend toward unisex invented names. The name's brief history and lack of etymological roots make it a purely modern creation, of interest to parents seeking a distinctive, contemporary-sounding name.
Demoni first appeared in U.S. birth records in 1997, around the start of the modern coinage trend. It may be a creative respelling of the French name Demi (short for Demetria) or an invented name formed by blending the fashionable -oni suffix with the initial De-. No historical roots in a specific language or culture have been identified.
