x1 offers/proffers x2 [offering] to x3 with conditions x4.
(x4 may be nu canja, nu pleji, etc.; an unconditional offering has the 'condition' of acceptance); x2 may be a specific object, a commodity (mass), an event, or a property; pedantically, for objects/commodities, this is sumti-raising from ownership of the object/commodity (= posfriti, posyselfriti for unambiguous semantics). See also canja, dunda, rinsa, vecnu, jdima, cnemu, pleji, vitke.
