LGBTQ is an initialism of lesbian, gay, bisexual, transgender and queer or questioning. It is an umbrella term, broadly referring to all sexualities, romantic orientations, and gender identities which are not heterosexual or cisgender.
Coming out of the closet, often shortened to coming out, is a metaphor used to describe LGBT people's self-disclosure of their sexual orientation, romantic orientation, or gender identity.
The LGBTQ community is a loosely defined grouping of lesbian, gay, bisexual, and transgender individuals united by a common culture and social movements. These communities generally celebrate pride, diversity, individuality, and sexuality. LGBT activists and sociologists see LGBT community-building as a counterweight to heterosexism, homophobia, biphobia, transphobia, sexualism, and conformist pressures that exist in the larger society. The term pride or sometimes gay pride expresses the LGBT community's identity and collective strength; pride parades provide both a prime example of the use and a demonstration of the general meaning of the term. The LGBT community is diverse in political affiliation. Not all people who are lesbian, gay, bisexual, or transgender consider themselves part of the LGBT community.
Heteronormativity is the concept that heterosexuality is the preferred or normal sexual orientation. It assumes the gender binary and that sexual and marital relations are most fitting between people of opposite sex.
LGBTQ slang, LGBTQ speak, queer slang, or gay slang is a set of English slang lexicon used predominantly among LGBTQ+ people. It has been used in various languages since the early 20th century as a means by which members of the LGBTQ+ community identify themselves and speak in code with brevity and speed to others. The acronym LGBT was popularized in the 1990s and stands for Lesbian, Gay, Bisexual, and Transgender. It may refer to anyone who is non-heterosexual or non-cisgender, instead of exclusively to people who are lesbian, gay, bisexual, or transgender. To recognize this inclusion, a popular variant, LGBTQ, adds the letter Q for those who identify as queer or are questioning their sexual or gender identity.
The following outline is provided as an overview of and topical guide to transgender topics.

The questioning of one's sexual orientation, sexual identity, gender, or all three is a process of exploration by people who may be unsure, still exploring, or concerned about applying a social label to themselves for various reasons. The letter "Q" is sometimes added to the end of the acronym LGBT ; the "Q" can refer to either queer or questioning.

Intersex people are born with sex characteristics that "do not fit the typical definitions for male or female bodies". They are substantially more likely to identify as lesbian, gay, bisexual, or transgender (LGBT) than endosex people. According to a study done in Australia of Australian citizens with intersex conditions, participants labeled 'heterosexual' as the most popular single label with the rest being scattered among various other labels. According to another study, an estimated 8.5% to 20% experiencing gender dysphoria. Although many intersex people are heterosexual and cisgender, this overlap and "shared experiences of harm arising from dominant societal sex and gender norms" has led to intersex people often being included under the LGBT umbrella, with the acronym sometimes expanded to LGBTI. Some intersex activists and organisations have criticised this inclusion as distracting from intersex-specific issues such as involuntary medical interventions.

It is predicated on the assumption that the norms and values of heterosexuality should be replicated and performed among homosexual people. Those who assert this theory claim homonormativity selectively privileges cisgender homosexuality as worthy of social acceptance.
