The hierarchical categorization of modern Chinese lexical categories can be presented by the lexical default value hierarchy. The default value of a word class represents the grammatical function characteristic of a word class, which refers to the ability of a word to perform syntactic roles. The biggest difference between the default values of syntactic roles of verbs and nouns in modern Chinese is their ability to act as predicates. The subclasses of verbs and nouns extend downward to include typical and atypical members, with the typical members inheriting all the default values of the parent class, and the atypical members inheriting some of the default values. From the longitudinal side of the word class hierarchy, the higher the level of the word class, the more it tends to be unmarked, with linguistic commonality, and the lower the level of the subclass, the more it tends to be marked, with individual linguistic characteristics; from the horizontal side, the fewer the subclasses violating the parent category’s default values, the more it tends to be unmarked, and the more the subclasses violating the parent category’s default values, the more it tends to be marked. |
