Dyke is an Old English word with historically related senses of something dug out and something built up; ditch is a variant, and dig belongs to the same family. Related German and Dutch forms contributed the built-up sense, initially referring to a city wall or fortification. Its derogatory use for a lesbian, originally found as bulldyke and attested by the 1930s, has an uncertain origin.
Etymology
