surname

n. name that is shared by members of a family, family name, last name

v. give a surname to

A family name, surname, last name, patronymic, or metronymic, is the part of a person's name indicating the family to which the person belongs. The use of family names is currently widespread in cultures around the world. Each culture has its own rules as to how these names are applied and used.In many cultures (notably most European, North American, and South American countries) the family name is typically the last part of a person's name. In many other cultures, however, the family name comes first. This order is often called the Eastern order because Europeans are most familiar with the examples of China, Vietnam, Japan and Korea. Because the family name is normally given last in English-speaking societies, the term last name is commonly used for family name.
