For example, Sportiche (2005) and Cecchetto and Donati (2015) propose that, in the case of verb-object idioms, the verb combines directly with the noun inside its DP complement, and the determiner is introduced higher up in the syntactic structure, or is late-adjoined. This seems to violate compositionality insofar as it is generally assumed that the semantic role of the determiner is to convert a noun to the appropriate semantic type to serve as the argument to the function denoted by the verb. In this paper, we establish a connection between this line of analysis and lines of work in semantics that have developed outside of the domain of idioms, particularly work on incorporation and a mixed formal and distributional semantic model developed in McNally (2017); McNally and Boleda (2017). This semantic work separates the composition of descriptive content from that of discourse referent introducing material; our proposal shows that this separation offers a particularly promising way to handle the compositional difficulties posed by idioms, including certain patterns of variation in intervening determiners and modifiers.application/pdfeng© De Gruyter Published version available at https://www.degruyter.com/view/j/ling.2019.57.issue-4/ling-2019-0016/ling-2019-0016.xml http://dx.doi.org/10.1515/ling-2019-0016info:eu-repo/semantics/articlehttp://dx.doi.org/10.1515/ling-2019-0016IdiomIncorporationEvent kindModificationReferenceinfo:eu-repo/semantics/openAccess
