USAGE NOTES
A reclaimed word is a word that was formerly used solely as a slur but that has been semantically overturned by members of the maligned group, who use it as a term of defiant pride. Queer is an example of a word undergoing this process. For decades queer was used solely as a derogatory adjective for gays and lesbians, but in the 1980s the term began to be used by gay and lesbian activists as a term of self-identification. Eventually, it came to be used as an umbrella term that included gay men, lesbians, bisexuals, and transgendered people. Nevertheless, a sizable percentage of people to whom this term might apply still hold queer to be a hateful insult, and its use by heterosexuals is often considered offensive. Similarly, other reclaimed words are usually offensive to the in-group when used by outsiders, so extreme caution must be taken concerning their use when one is not a member of the group.
