A term used to describe someone who acknowledges and appreciates differences in people and groups. This is someone who is a safe and open person to talk to and someone who is willing to stand up for the rights and well-being of others.


An acronym for "Assigned Male at Birth."




Someone who does not experience sexual attraction. There is considerable diversity in this community; each individual experiences things like relationships, attraction, and arousal somewhat differently.


Someone who is attracted to both men and women. A person who experiences sexual, romantic, physical, and/or spiritual attraction to people of their own gender as well as another gender.

A term used to describe an individual, regardless of sexual orientation, who chooses to dress in the “opposite” gender clothing.


A theatrical performance adopting gendered clothing and behaviors (usually not associated with one's own identity) for entertainment and expression. Drag does not indicate the performer's sexual orientation or gender identity.


A sociological construct (usually taught as a binary) defining the collection of characteristics that are culturally associated with maleness or femaleness; masculine and feminine constitute this.

Gender Expression

Gender Identity

One’s internal sense of being a man, woman, neither of these, both, or other gender(s).

A term used to describe someone who is attracted to those on the same side of the sex and gender binary. The term's pathological connotation makes many LGBTQ+ people hesitant to identify with it. 


A general term used for a variety of conditions in which a person is born with a reproductive or sexual anatomy that doesn’t seem to fit the typical definitions of female or male.


An identity claimed by those whose gender identity does not fit neatly into the culturally expected man/woman gender binary. Non-binary people may feel the desire to express a fluid and changing identity or to challenge social norms around gender.

A biological term dividing a species into male or female, usually on the basis of chromosomes (XX = female, XY = male). Hormone levels, secondary sex characteristics, and internal and external genitalia may also be considered criteria.

Sexual Orientation

A person’s physical, romantic, emotional, aesthetic, and/or other form of attraction to others.


An umbrella term for those individuals whose gender identity does not match with that assigned for their physical sex. Importantly, this term does not tell us anything about someone’s sexual orientation.


The process of changing one's sex or gender, socially (through outward gender expression, pronouns) or medically (hormones/surgery).


A term used to describe a person who identifies psychologically as a gender/sex other than the one to which they were assigned at birth. This individual may use hormones and/or surgery to help their physical body match their inner sense of gender/sex.


A term linking one's status as undocumented with their queer identity to show that not only are they intersectional, but inseparable.
