Identification is the process of recognizing who or what someone or something is. When you show identification at the airport, you're proving you are who you say you are, usually with a document like a passport or driver's license. Police officers might ask witnesses for an identification of a suspect, meaning they want to know if the witnesses can recognize or name the person.

A scientist might identify a rare bird by its distinctive markings. A doctor identifies an illness by its symptoms. Your teacher might ask you to identify the main character in a story.

In psychology, identification means feeling a strong connection with someone and adopting their qualities or behaviors. A young athlete might identify with their coach, wanting to develop the same determination and skills.

The word can also mean a card or document that proves who you are. You might carry an identification card for your school library, or your parents might need to show identification to pick up a package. This kind of identification usually includes your name, photo, and other details that confirm your identity.
