early 13c., "small door or gate," especially one forming part of a larger one, from Anglo-French wiket, Old North French wiket (Old French guichet, Norman viquet) "small door, wicket, wicket gate," probably from Proto-Germanic *wik- (source also of Old Norse vik "nook," Old English wican "to give way, yield"), from PIE root *weik- (2) "to bend, to wind." The notion is of "something that turns." Cricket sense of "set of three sticks defended by the batsman" is recorded from 1733; hence many figurative phrases in British English.
