Gender Identity: One’s internal sense of being male, female, neither of these, both, or another gender(s). Everyone has a gender identity, including you. For transgender people, their sex assigned at birth and their own internal sense of gender identity are not the same. Female, woman, and girl and male, man, and boy are also not necessarily linked to each other but are just six common gender identities.

Gender Expression/Presentation: The physical manifestation of one’s gender identity through clothing, hairstyle, voice, body shape, etc. Many transgender people seek to make their gender expression (how they look) match their gender identity (who they are), rather than their sex assigned at birth.

Sex Assigned at Birth: The assignment and classification of people as male, female, intersex, or another sex based on a combination of anatomy, hormones, chromosomes.
