Explanation
Are you between the ages of 13 and 19? If so, you're a teen! Teen is a less-formal way to say teenager. You can use this informal word as a noun or an adjective, so you might talk about teen literature, teen rebellion, teen movies, or teen romance—anything that has to do with teenagers. If you're 11, you may be eagerly anticipating your teen years; if you happen to be 37, you certainly remember being a teen, either fondly or not. The teen years are also known as adolescence.
