From PIE *ǵʰeh₁- (to leave) — its past tense 'went' was pirated from 'wend' (to turn), making it wildly suppletive.
To move from one place to another; to travel or proceed in a specified direction.
From Old English 'gān' (to go, walk, move), from Proto-Germanic *gāną, from the PIE root *ǵʰeh₁- meaning 'to leave, to go away.' This is one of the most suppletive verbs in English: its past tense 'went' comes from an entirely different verb — Old English 'wendan' (to turn, to go), which displaced the original past tense 'eode.' Such radical suppletion, where a verb borrows its past tense from an unrelated word, is rare in the world's languages. Key
