jackpot
UK: ˈdʒækpɒt | US: ˈdʒækpɑːt
n. a large cash prize in a game or lottery
n. an unexpected or massive success or reward
n. (historical) the stakes accumulated in a game until won
The term "jackpot" originated in 19th-century poker, where a hand (often a pair of jacks or better) was required to open betting. The "pot" grew until someone could meet this requirement, making it a coveted prize. Over time, "jack" (a generic term for a man) combined with "pot" (the pooled stakes) evolved to signify any large, accumulated reward, especially in gambling or contests.
