"LGBT", or "GLBT", is an initialism that stands for lesbian, gay, bisexual, and transgender. In use since the 1990s, the term is an adaptation of the initialism "LGB", which was used to replace the term "gay" - when referring to the community as a whole - beginning in about the mid-to-late 1980s. While the movement had always included all LGBT people, the one-word unifying term in the 1950s through the early 1980s was "gay" (see Gay liberation). Later, this was expanded by many groups to "lesbian and gay", to be more representative. In the late eighties and early nineties, "queer" was also reclaimed as a one-word alternative to the ever-lengthening string of initials, especially when used by radical political groups.
