A given name (also known as a forename or first name) is the part of a personal name that identifies a person, potentially with a middle name as well, and differentiates that person from the other members of a group (typically a family or clan) who have a common surname. The term given name refers to a name usually bestowed at or close to the time of birth, usually by the parents of the newborn. A Christian name is the first name which is given at baptism, in Christian custom.
In informal situations, given names are often used in a familiar and friendly manner. In more formal situations, a person's surname is more commonly used. In Western culture, the idioms "on a first-name basis" and "being on first-name terms" refer to the familiarity inherent in addressing someone by their given name.
