The lexical semantics of lexical categories (2018-2023)
European Research Council Consolidator grant
Summary of project
The distinction between the major lexical categories of a noun, verb and adjective figures into myriad linguistic generalisations and has been a centre of gravity in the study of language since antiquity.
Notwithstanding their importance, lexical categories are poorly understood (see eg Baker & Croft 2017). Outstanding is whether there are generalisations about the meanings words in the major categories have.
Many have claimed there are, and proposed theories linking meaning and category, in a one to one fashion. Such theories have been criticized, however, in light of clear counterexamples, and consequently, the search for a universal link between meaning and category is perceived by many to have been unsuccessful (see von Fintel & Matthewson 2008).
This project recasts the search for a link, in the spirit of recent work (Francez & Koontz-Garboden 2017: Chapter 5), not as one for a one-to-one mapping, but for constraints on meaning induced by category.
The project targets a domain where the set of relevant meanings is small, but where there is variation in category: property concept sentences—sentences like
(1) He is very clever
whose main predicate is an adjective, or,
(2) akwai shi da waayoo 'He is very clever' (lit: He exists with cleverness; Hausa; Newman 2000:179)'
whose main predicate is not an adjective, but is translated by a sentence whose main predicate is an adjective in languages with a large class of them.
Although (1) and (2) have the same meaning, their component parts do not. Recent work shows that the words in property concept sentences that introduce the descriptive content (clever in (1), waayoo (2))–property concept words–vary in meaning, not just in category (Dixon 1982).
With three postdocs, this project draws on a 200-language typological survey and in-depth fieldwork to examine the cross-classification of meaning and category in property concept words to shed light on the semantic nature of nouns, verbs, and adjectives generally.
