This chapter provides an overview of noun incorporation in broad terms, examining nominals found either within or strictly adjacent to predicates from numerous languages. Syntactic issues have shifted from an earlier debate about whether noun incorporation was an operation in the lexicon or syntax to more recent discussion about whether noun incorporation is a narrow syntax or PF operation. Other issues concern whether phrases or just heads can incorporate. If phrases incorporate, are they phrasal at the point of incorporation? AGREE analyses examine the trigger for incorporation. A number of analyses posit that there is no movement of the nominal at all (pseudo noun incorporation), and utilize an adjacency relation between the verb and incorporated nominal. It remains clear that languages show similar cross‐linguistic properties in noun incorporation, even to the extent that language‐internal differences are often similar, often relating to verb class. The expansion of the set of empirical data from semantic analyses and other work continues to lead toward refinements.
