Etymology

Origin of identification

First recorded in 1635–45; identi(fy) + -fication

Explanation

Identification is what you show when someone wants proof of who you are. When you get pulled over by a cop for speeding, you better have your driver’s license on you as your form of identification! Identification isn’t just the card or passport you carry around in your wallet to prove who you are to others. You can also have an identification with a person if you share common beliefs, traditions, or values; then you can say that you identify with that person. Identification can also mean the process of recognizing or identifying something. You may have to wait to adopt that stray dog until the pound has put the pooch through an identification process, trying to see if he already belongs to another family.
