[I]n all likelihood, not the etymon of ME cokeney 'milksop, simpleton; effeminate man; Londoner,' which is rather a reshaping of [Old French] acoquiné 'spoiled' (participle). However, this derivation poses some phonetic problems that have not been resolved.The accent so called from 1890, but the speech peculiarities were noted from 17c. As an adjective in this sense, from 1630s.
