Nominalizations: The Case of Nominalizations of Modal Predicates Friederike Moltmann CNRS-IHPST and NYU Nominalizations describing events and tropes have a received considerable interest in the semantic (and philosophical) literature. By contrast nominalizations of modal verbs and the modal objects they describe have received little if any attention in the literature so far. This paper is a case study of nominalizations of the sort 'need', 'possibility', 'necessity', as well as nominalizations arguably describing the same sorts of modal objects, namely 'permission', 'obligation', 'invitation', and 'offer'. The paper will give a general caracterization of the modal objects such nominalizations describe and address the question of how familiar semantic nominalization strategies may fare in regard to how the semantics of the nominalization may be obtained from the underlying predicate. Those strategies include the Davidsonian view that takes nominalizations to pick up an implicit argument of the underlying predicate, the Kimian or pleonastic view that takes nominalizations to introduce 'new' semantic objects into the semantic structure that would not have been present otherwise, and the truthmaker view, which takes nominalizations to stand for the truthmakers of the corresponding underlying sentences. The paper will furthermore address the question of the importance of modal objects in the semantics of sentences and for the semantics of modality in particular.
