This research report discusses a set of Indonesian predicates exemplified by mau ‘want’ and suka ‘like’. I demonstrate with several diagnostics that these morphemes occur as either auxiliary or verb, and note that the availability of the auxiliary reading has been overlooked in recent literature. Since mau and suka belong to the set of so-called crossed control predicates, the lexical ambiguity discussed here has implications for potential analyses of crossed control sentences. I suggest that the auxiliary reading for mau, suka, and other predicates must be carefully ruled out before the existence of a crossed reading can be established.
