The short story
Arias is a Spanish surname derived from the medieval personal name Arias. In a hereditary naming system, it could mark a family descended from an ancestor who used that name, although the surname does not preserve a simple literal “son of” ending. The personal name’s deeper origin is disputed, and Arias also appears in Sephardic and converted-family histories, so one explanation should not be imposed on every bearer. Aria and older Arias spellings occur in related records. Parent’s name is the likely catalog type: the personal-name source is strong, while the wider historical pathways remain mixed.
