A middle name is an additional name given to a person, typically placed between their first name and last name. It is often used to honor family members, carry on traditions, or provide a unique identity. In many cultures, having a middle name is common, but it is not universally practiced. Middle names can serve various purposes, such as distinguishing individuals with common first and last names. They may also reflect cultural or religious significance. Some people choose to use their middle name in professional settings or prefer it over their first name for personal reasons.
