The word has probable cognates in other Germanic languages, such as German ficken (to fuck); Dutch fokken (to breed, to strike, to beget); dialectal Norwegian fukka (to copulate), and dialectal Swedish fokka (to strike, to copulate) and fock (penis).[2] This points to a possible etymology where Common Germanic fuk– comes from an Indo-European root meaning "to strike", cognate with non-Germanic words such as Latin pugnus "fist".[2] By reverse application of Grimm's law, this hypothetical root has the form *pug–. In early Proto-Germanic the word was likely used at first as a slang or euphemistic replacement for an older word for intercourse, and then became the usual word for intercourse.
