Etymology
Origin of dyke
First recorded in 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 preexisting dyke; other hypothesized connections, such as with diked out or dike “ditch,” are dubious on semantic grounds
