Gradability, scale structure, and the division of labor between nouns and adjectives: The case of Japanese

要旨

Japanese has three major “adjective-like” word classes, which roughly correspond to “adjectives”, “adjectival nouns”, and “precopular nouns” in Martin’s (1975) A Reference Grammar of Japanese. This work explores how the three classes contrast semantically, paying special attention to the notion of gradability. Their scale-structural characteristics, in comparison with the English adjective class, will be examined, aiming to contribute to a better understanding of how languages may contrast in terms of (i) how different kinds of stative predicates divide the labor in encoding different kinds of state concepts, and (ii) how the niche of their noun class (as a major part-of-speech) is delimited. The major findings include (i) that “adjectives” and “adjectival nouns” have a strong tendency to encode relative gradable concepts, (ii) that “precopular nouns” tend to be nongradable, and (iii) none of the three Japanese classes is closely tied to the feature of absolute gradability.
