Demi is usually a short form of Demetria, the Greek name derived from Demeter, goddess of the harvest, so it is read as "follower of Demeter"; it also matches the French word demi, "half". Actresses Demi Moore and Demi Lovato made the short form familiar across the United States. Demi entered the top 1000 in 2009, peaked at number 339 in 2020 and ranks number 381 in 2025.
