LET'S, LEMME, HASTA/HAFTA/HADDA, GOTTA, USETA, WANNA, BE SPOSETA, AND

What'd she hafta do? : What'd she have to do? What've we gotta do? : What have we got to do? What'd she useta do it with? : What'd she use to do it with?* What'd he wanna do? : What'd he want me to do?	He has to. They have to. She's got to. Pronounced like the verb use*--with final [z].
What was it bound to do? : Were they bound to carry out that agreement? What was it sposeta do? : What was it supposed to do?
