Nicholas is a male name, the Anglophone version of an ancient Greek name in use since antiquity, and cognate with the modern Greek Νικόλαος, Nikolaos. It originally derived from a combination of two Greek words meaning 'victory' and 'people'. In turn, the name means "victory of the people." The name has been widely used in countries with significant Christian populations, owing in part to the veneration of Saint Nicholas, which became increasingly prominent in Western Europe from the 11th century.
