Difference between gay and transgender

Being gay refers to a person's sexual orientation, specifically when someone is attracted to individuals of the same sex. On the other hand, being transgender refers to a person's gender identity, which may not align with the sex they were assigned at birth.

As adjectives the difference between transgender and gay is that transgender is having a gender identity (self-image) which is the opposite of one's physical sex: being physically male but identifying as female, or vice versa.
