noun Slang: Disparaging and Offensive.

a contemptuous term used to refer to a lesbian.

Origin of dyke

1940–45; earlier in form bulldike (with a variant bulldagger); of obscure origin; claimed to be a shortening of morphodyke (variant of morphodite, a reshaping of hermaphrodite), though morphodyke is more likely a blend of morphodite and a pre-existing dyke; other hypothesized connections, such as with diked out or dike “ditch,” are dubious on semantic grounds

Related formsdyk·ey, adjective, dyk·i·er, dyk·i·est.

Usage note

The terms dyke and bull dyke are used with disparaging intent and are perceived as insulting. However, they have been adopted as positive terms of self-reference by young or radical lesbians and in the academic community. In the mainstream homosexual community, gay and lesbian remain the terms of choice.

Word Origin and History for dyke

dyke

1931, American English, perhaps a shortening of morphadike, dialectal garbling of hermaphrodite; but bulldyker "engage in lesbian activities" is attested from 1921, and a source from 1896 lists dyke as slang for "the vulva."

[T]he word appears first in the long forms, bulldiker and bulldyking, both used in the 1920s by American blacks. No African antecedents have been found for the term, however, which leads to the possibility that this is basically just another backcountry, barnyard word, perhaps a combination of BULL and DICK. [Rawson]

dike

Old English dic "trench, ditch; an earthwork with a trench; moat," from Proto-Germanic *dik- (cf. Old Norse diki "ditch, fishpond," Old Frisian dik "mound, dam," Middle Dutch dijc "mound, dam, pool," Dutch dijk "dam," German Deich "embankment"), from PIE root *dheigw- "to pierce, fasten" (cf. Sanskrit dehi- "wall," Old Persian dida "wall, stronghold, fortress," Persian diz).

At first "an excavation," later (late 15c.) applied to the resulting earth mound; a sense development paralleled by cognate forms in many other languages. This is the northern variant of the word that in the south of England yielded ditch (n.).
