Word Origin and History for stir-crazy

1908, from crazy + stir "prison" (1851), probably from Start Newgate (1757), prison in London, later any prison (1823), probably from Romany stardo "imprisoned," related to staripen "a prison." Mid-19c. sturaban, sturbin "state prison" seem to be transitional forms.
