The Lexicalist Hypothesis: Both Wrong and Superfluous Benjamin Bruening, University of Delaware (
[email protected]) draft, February 17, 2017; comments welcome Abstract The Lexicalist Hypothesis, which says that the component of grammar that produces words is distinct and strictly separate from the component that produces phrases, is both wrong and superfluous. It is wrong because (1) there are numerous instances where phrasal syntax feeds word formation; (2) there are cases where phrasal syntax can access sub-word parts; and (3) claims that word formation and phrasal syntax obey different principles are not correct. The Lexicalist Hypothesis is superfluous because where there are facts that are supposed to be accounted for by the Lexicalist Hypothesis, those facts have independent explanations. The model of grammar that we are led to is then the most parsimonious one: there is only one combinatorial component of grammar that puts together both words and phrases. 1 Introduction The Lexicalist Hypothesis, usually attributed to Chomsky 1970, is a foundational hypothesis in numerous current approaches to morphology and syntax, including Head-Driven Phrase Structure Grammar (HPSG), Lexical Func- tional Grammar (LFG), Simpler Syntax (Culicover and Jackendoff 2005), various versions of the Principles and Parameters and Minimalist models, and others.1 The basic tenet of the Lexicalist Hypothesis is that the system of grammar that assembles words is separate from the system of grammar that assembles phrases out of words. The combinatorial system that produces words is supposed to use different principles from the system that produces phrases. Additionally, the word system is encapsulated from the phrasal system and interacts with it only in one direction, with the output of the word system providing the input to the phrasal system.
