x1 is/does x2 as much as x3 wants them to.
In general usage, the x3 is expected to be left to context: «.e’a do djirai lo ni citka» ‘you can eat as much as wanted’ (i.e. as much as *you* want), but it can be stated explicitly for completeness. See also cumrai ‘as … as possible’ , and also tankomo ‘as … as …’, the general case.
