Measure phrases (MPs, e.g., “two pounds”) appear in a wide variety of environments: nominal, adjectival, adpositional, and verbal structures. The goal of the chapter is to present an overview of the variety of constructions involving MPs as well as the different treatments that were proposed for these structures. Accordingly, the chapter reviews the internal structure of measure expressions as well as the function (predicate nominal, modifier or argument) and position of MPs inside the larger structures that contain them. The structures to be discussed include positive and differential MPs, which appear with adjectives as well as in compound, partitive, and pseudopartitive constructions with nominals. The chapter also addresses variation in the acceptability of MPs, both language‐internally and across languages, as well as the cross‐linguistically distinct realizations of structures that contain MPs. Other topics to be discussed are issues specific to spatial (“twenty miles”) and temporal measure expressions (“twenty minutes”) as well as classifier and container constructions.
