Lesbian

Lesbian describes a sexual orientation in which a woman experiences enduring romantic and/or sexual attraction primarily or exclusively to other women. As with other sexual orientations, major clinical and advocacy definitions describe it as a stable pattern of attraction rather than a behavior or a choice (APA). It is one of the two classical monosexual orientations (attraction directed toward a single gender) alongside heterosexuality, and stands in contrast to plurisexual orientations such as bisexuality and pansexuality, which describe attraction to more than one gender.

GLAAD and the Human Rights Campaign both define "lesbian" as a woman who is emotionally, romantically, or sexually attracted to other women, and both organizations note that the word functions as a noun and an adjective (a lesbian, a lesbian relationship, lesbian culture) (GLAAD, HRC). "Gay" is sometimes used interchangeably with "lesbian" for women, and GLAAD's own style guidance notes that "lesbian" is often the preferred, more specific term for women even though "gay" remains grammatically applicable to any same-gender attraction (GLAAD).

Institutional definitions center on the pattern of attraction itself rather than on behavior or relationship history. The American Psychological Association's guidance on sexual orientation holds that a person's orientation is defined by attraction rather than by whether it has been acted on, and that most people report little or no sense of having consciously chosen their pattern of attraction (APA).

Examples

Lesbian is a specific term surrounded by broader ones, and most of its usage questions are about which of them to reach for.

What the term covers. A woman whose enduring romantic, sexual or both forms of attraction run primarily or exclusively to other women. It works as noun and adjective alike (a lesbian, a lesbian relationship, lesbian history) and the attraction defines it rather than any relationship history: someone can know they are a lesbian without ever having dated a woman.

What the term does not cover. Sapphic and "WLW" (woman-loving-woman) are broader umbrellas that also gather bisexual and other non-monosexual women, and in some usage non-binary people. Homosexuality is the older clinical term covering both sexes. Gynesexuality names attraction to women without specifying the speaker's own gender, which "lesbian" does specify. Gender expression is unrelated: masculinity and femininity vary independently of who someone is attracted to.

How the word is used. Until the mid-nineteenth century it meant only "of Lesbos", the island of the poet Sappho. English applied it to relationships between women from 1870, the National Medical Dictionary used it adjectivally by 1890, and it was recorded as a noun by 1925, inside a sexological frame that treated female same-sex attraction as pathology. GLAAD now recommends it over "homosexual" as the specific, community-preferred term.

History

Before the mid-19th century, "lesbian" referred only to the island of Lesbos and its products. The word's sexual sense entered documented use in 1870, when English writing first applied it to erotic relationships between women; by 1890 the National Medical Dictionary used "lesbian" as an adjective to describe tribadism, and by 1925 it was recorded as a noun for the female equivalent of "sodomite" (Wikipedia). Physicians and sexologists, including Richard von Krafft-Ebing and Havelock Ellis, folded the term into a medical framework that approached female same-sex attraction as a form of insanity through the early 20th century (Wikipedia).

Visible lesbian subcultures persisted despite this framing: Radclyffe Hall's 1928 novel The Well of Loneliness, prosecuted for obscenity in Britain shortly after publication, became what scholars describe as the crystallizing moment for a visible modern English-language lesbian subculture (Wikipedia). Organized advocacy followed in 1955, when the Daughters of Bilitis formed in San Francisco as the first lesbian rights organization in the United States; the group began publishing The Ladder, the first nationally distributed lesbian magazine, the following year (History). As gay and lesbian activism grew more organized and vocal through the 1960s and 1970s, lesbian feminism developed a distinct political voice, producing periodicals such as The Furies and Sinister Wisdom (Wikipedia).

Demographics & research

Survey estimates of lesbian identification vary by country, methodology, and survey wave. Gallup's 2024 U.S. tracking survey found that 1.4% of American adults identified as lesbian, alongside 2.0% who identified as gay, 5.2% as bisexual, and 1.3% as transgender, within an overall LGBTQ+ identification rate of 9.3% (Gallup). Pew Research Center's 2025 survey of LGBTQ adults found that gay men and lesbians together make up about four in ten (40%) of the U.S. LGBTQ population, with most of the remainder identifying as bisexual (Pew Research Center).

Terminology & related identities

"WLW" (woman-loving-woman) is a broader umbrella sometimes used alongside "lesbian" to include bisexual and other non-monosexual women in women-attracted-to-women spaces. "Sapphic," from Sappho herself, functions similarly as an inclusive umbrella covering women and, in some usage, nonbinary people attracted to women. "Homosexual" is the older clinical-register term for same-gender attraction in either sex; GLAAD's style guidance recommends "gay," "lesbian," or "queer" over "homosexual" when describing people, reserving the older term for clinical or historical context because of its origin as a 19th-century psychiatric label (GLAAD). "Lesbian" remains the specific, community-preferred term for women, distinguishing it from the plurisexual labels bisexual and pansexual. The corresponding romantic-orientation term (describing romantic rather than necessarily sexual attraction to women) is "homoromantic"; a woman who identifies as lesbian and also as asexual or graysexual is describing an absence or infrequency of sexual attraction alongside a romantic or aesthetic orientation toward women.

Common misconceptions

The Trevor Project and the APA both address the misconception that sexual orientation must be behaviorally confirmed: a person does not need direct sexual experience to know their orientation, and most people experience little or no sense of having chosen their pattern of attraction in the first place (The Trevor Project, APA). The Trevor Project also corrects a persistent appearance stereotype, stating plainly that "gay people aren't automatically effeminate, and lesbian women aren't automatically masculine," and that gender expression varies independently of sexual orientation (The Trevor Project).
