姓氏在英语中用法怎么说

In English, a person's last name (also called a surname or family name) is usually used in conjunction with their first name. For example, if a person's name is John Smith, "Smith" is the person's last name and "John" is their first name. The last name is typically used to identify a person within a family or group, and is usually inherited from one's parents.

In English, a person's last name is typically mentioned after their first name. For example, you might introduce yourself as "Hi, my name is John Smith." In written communication, a person's last name is often followed by their first initial. For example, you might sign a letter "Sincerely, John S."

It's worth noting that in some cultures, the order of a person's given name and surname may be different from the Western convention. In some parts of Asia, for example, the surname is typically mentioned before the given name.
