Alf is a deeply rooted masculine name of Old Norse origin, derived from the word meaning "elf" or "supernatural being." Historically linked to Northern European mythology, the name maintains a strong but infrequent presence in the USA, often associated with immigrant heritage. Globally, Alf is strictly defined as a male name, carrying connotations of antiquity and traditional strength. Its short, decisive structure contributes to a robust and straightforward mood, projecting reliability and a vintage charm. This concise name holds a classic appeal due to its powerful etymological background.
