Lopez

The origin of the surname Lopez

López means “son of Lope,” from the Latin lupus, “wolf.”

What kind of surname is Lopez?

As a patronymic surname, the surname Lopez was formed from a father's or ancestor's personal name — the single largest way hereditary surnames arose across Europe. Before family names became fixed, a man was often known as the son of his father (for example “John, son of Robert”), and over generations that link hardened into an inherited surname. Different cultures marked the relationship differently: English and Scandinavian names added “-son”, Irish and Scottish used “Mac” or “O’”, Slavic languages added “-ov”, “-ev” or “-vich”, and many languages simply reused the father's name unchanged. A patronymic surname therefore points back to a founding ancestor rather than a place or an occupation.

How Spanish surnames work

Spanish surnames classically use the patronymic suffix “-ez” meaning “son of” — González (“son of Gonzalo”), Rodríguez, Martínez, Fernández. Alongside these are locational names (often with “de”) and occupational or descriptive names. Spanish-speaking cultures also traditionally carry two surnames, the father's followed by the mother's, so a full name preserves both family lines.
