Probably the most successful example in recent history, queer used to be exclusively a homophobic insult but has undergone a pretty impressive reappropriation by academics and the LGBTQ+ community. Queer is still considered problematic by some, but in the grand scheme of things, the word has evolved into a sort of self-affirming umbrella term for nonnormative gender and sexual identities. Today it can be found in contexts as lighthearted as the title of the TV series Queer Eye for the Straight Guy and as formal as one of the gender options listed on a job application, next to male and female.
