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. 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.
By contrast, a surname (also known as a family name, last name, or gentile name) is normally inherited and shared with other members of one's immediate family. Regnal names and religious or monastic names are special given names bestowed upon someone receiving a crown or entering a religious order; such a person then typically becomes known chiefly by that name.
Personal name#Name order
The order given name – family name, commonly known as Western name order, is used throughout most European countries and in countries that have cultures predominantly influenced by European culture, including North and South America; North, East, Central and West India; Australia, New Zealand, and the Philippines.
The order family name – given name, commonly known as Eastern name order, is primarily used in East Asia (for example in China, Japan, Korea, Taiwan, Singapore, and Vietnam, among others, and by Malaysian Chinese), as well as in Southern and North-Eastern parts of India, and as a standard in Hungary. This order is also used to various degrees and in specific contexts in other European countries, such as Austria and adjacent areas of Germany (that is, Bavaria), and in France, Belgium, Greece and Italy, possibly because of the influence of bureaucracy, which commonly puts the family name before the given name.
