LGBT is an initialism connected with human sexuality. It means lesbian, gay, bisexual, and transgender, but it can refer to a community of people who are not heterosexual or cisgender. It is a word which has been used since the 1990s, and was a change from the previous acronym LGB or the group of words gay community, because many people in the LGBT community did not think that the group of words accurately described everyone it was referring to.
