Word Origin for fuck

C16: of Germanic origin; related to Middle Dutch fokken to strike


The use and overuse of fuck in the everyday speech of many people has led, to some extent, to a lessening of its impact as an expletive. However, the word still retains its shock value, although it is less now than it was when the critic Kenneth Tynan caused controversy by saying it on British television in 1965
