Costa

The origin of the surname Costa

Costa was given to someone who lived on a coast or hillside.

What kind of surname is Costa?

As a toponymic (locational) surname, the surname Costa originally described where its bearer lived or came from — a village, region, landscape feature or landmark. When people moved from one place to another, neighbours often identified the newcomer by their place of origin, and that association became a lasting family name. Some toponymic surnames name a specific town or county; others describe the local terrain, such as a hill, wood, field, ford or bridge beside which a family lived. These names are a kind of map of migration and settlement, recording where earlier generations put down roots.

How Italian surnames work

Italian surnames are richly varied and often end in a vowel. Many are patronymic, sometimes marked by “di” or “De” (“son of / of the family of”), as in De Luca; others are occupational (Ferrari, “smith”), descriptive (Rossi, “red-haired”) or locational. Plural or “-i” endings frequently signal “the family of”, and regional dialects across Italy produced an enormous diversity of names.
