Transgender is a term used to describe people who may act, feel, think, or look different from the gender that they were born with. The word transgender is used to include many groups of people who share one important "trait" (a way of feeling or behaving) but may not be the same in other ways. The common trait for transgender people is that they call themselves "transgender" and feel that their given gender is not quite right. Sometimes the word "transgender" is also used by people who prefer it to the word "transsexual".
