The past tense of 'bet,' meaning to have wagered money or something of value on the outcome of an uncertain event.
From Middle English 'betten,' possibly from a Scandinavian source. The '-ed' suffix marks the past tense; 'bet' can also serve as past tense in modern usage, though 'betted' remains common in British English.
Interestingly, 'betted' is actually disappearing from English—most modern speakers say 'I bet' for both present and past tense, showing how language naturally simplifies itself over generations, especially with irregular verbs.
