Bet or betted? What’s the past tense of “bet”?
I bet on the underdog and won.
She bet all her savings on the horse race.
The word (and verb) bet, which is defined in the Oxford Learner’s dictionary as, “to risk money on a race or an event by trying to predict the result“, mostly uses one form for all its tense and participle forms, i.e., bet. Simply put, the safe bet is to stick to bet as both the simple past and past participle forms of bet. Betted, though sometimes accepted, is for the most part considered archaic and nonstandard.
