A surname is a name added to a given name and is part of a personal name. In many cases, a surname is a family name and many dictionaries define "surname" as a synonym of "family name". In the western hemisphere, it is commonly synonymous with "last name", since it is usually placed at the end of a person's given name. In most Hispanophone and Lusophone countries, two or more last names (or surnames) may be used.
