Since Carlson 1977 argued for them in the analysis of genericity, kinds or types modeled as entities or primitives in "rich" type theories (respectively) have come to have an increasing role in the analysis of a wide variety of natural language semantic phenomena (see e.g. Zamparelli 1995, Boleda & McNally 2004, Gehrke 2012, Aguilar & Zwarts 2012, Anderson & Morzycki 2013 for kinds; Barwise & Perry 1983, Ranta 1994, Cooper 2005, Asher 2011, Chatzikyrakidis & Luo 2016 for rich type theories). Kind and type descriptions play an active role in semantic composition crucially in interaction with token-referring expressions. In the field of syntax, since the early 1990s multiple approaches have distinguished two varieties of structures: roots and functional structure (see e.g. Borer 2003 for an early overview; see Theoretical Linguistics vol. 40.3/4, 2014, for more recent discussion). The goal of this workshop is to bring these two strands of work together and address the following question: Can an explicit effort to relate the semantic modeling of type/token interactions to the syntactic modeling of root/functional structure interactions improve our understanding of the syntax/semantics interface?
