Gay

Refers to a man who has a romantic and/or sexual orientation towards men. Also a generic term for lesbian and gay sexuality - some women define themselves as gay rather than lesbian. Some non-binary people may also identify with this term.

Gender

Often expressed in terms of masculinity and femininity, gender is largely culturally determined and is assumed from the sex assigned at birth.

Gender dysphoria

Used to describe when a person experiences discomfort or distress because there is a mismatch between their sex assigned at birth and their gender identity.

This is also the clinical diagnosis for someone who doesn’t feel comfortable with the sex they were assigned at birth.

​Gender expression

Gender identity

A person’s innate sense of their own gender, whether male, female or something else (see non-binary below), which may or may not correspond to the sex assigned at birth.

Gender reassignment

Another way of describing a person’s transition. To undergo gender reassignment usually means to undergo some sort of medical intervention, but it can also mean changing names, pronouns, dressing differently and living in their self-identified gender.

Gender reassignment is a characteristic that is protected by the Equality Act 2010, and it is further interpreted in the Equality Act 2010 approved code of practice. It is a term of much contention and is one that Stonewall's Trans Advisory Group feels should be reviewed.​ 

Gender Recognition Certificate (GRC)

This enables trans people to be legally recognised in their affirmed gender and to be issued with a new birth certificate. Not all trans people will apply for a GRC and you currently have to be over 18 to apply.

You do not need a GRC to change your gender markers at work or to legally change your gender on other documents such as your passport.

​H

Intersex people may identify as male, female or non-binary.

Passing

If someone is regarded, at a glance, to be a cisgender man or cisgender woman.

Platonic partnerships

People who are on the ace and/or aro spectrum may have platonic partnerships. These are relationships where there is a high level of mutual commitment which can include shared life decisions, shared living arrangements, and co-parenting of children. These partnerships can include more than two people. Like allosexual and alloromantic people, ace and aro spectrum people may be monogamous or polyamorous.

Pronoun

Q

Queer

Queer is a term used by those wanting to reject specific labels of romantic orientation, sexual orientation and/or gender identity. It can also be a way of rejecting the perceived norms of the LGBT community (racism, sizeism, ableism etc).

​​Transitioning

The steps a trans person may take to live in the gender with which they identify. Each person’s transition will involve different things. For some this involves medical intervention, such as hormone therapy and surgeries, but not all trans people want or are able to have this.

Transitioning also might involve things such as telling friends and family, dressing differently and changing official documents.

This term is still used by some although many people prefer the term trans or transgender.​

U

Undetectable

HIV medication (antiretroviral treatment, or ART) works by reducing the amount of the virus in the blood to undetectable levels. This means the levels of HIV are so low that the virus cannot be passed on. This is called having an undetectable viral load or being undetectable.
