Definition & Meaning of "dyke"in English

What is the origin of the term "dyke" and how is it used?

Dyke is a slang term for a lesbian that first appears in print in the early 20th century, though it likely circulated in speech earlier. Its exact origin is uncertain, but it may come from a shortening of "bulldyke," which itself was used as a derogatory term for masculine women. Over time, dyke came to specifically signal lesbians who exhibit or embrace masculine traits, behavior, or appearance. Historically it was very insulting, often used to shame or threaten women, but from the 1970s onward, some lesbian communities reclaimed it as a badge of pride. Despite that, it remains context-sensitive: outsiders using it can still cause offense, while within certain LGBTQ+ spaces it can be neutral or empowering.
