Modern English
surname

Before “surname” settled into meaning a family name, it was simply an extra label—something placed “over” your ordinary Christian name. Medieval French speakers had surnoun, built from sur, “above,” and nom, “name”; English speakers partly translated that pattern and produced surname around 1300. The label might advertise a trade, a birthplace, an achievement, or a physical trait, which is why names such as Spencer began as occupational surnames for household stewards. Norman nobles in England were using hereditary surnames by the early 12th century, while ordinary people adopted them more widely during the 13th and 14th centuries. So your surname is, linguistically, a name perched on top of another name—an old medieval second story that eventually became the family foundation.
