Haida, a language isolate spoken in the northwestern coast of North America, uses classifiers on verbs to denote the semantic category of the referent of a noun that functions as the subject of an intransitive clause or the object of a transitive clause. The present study shows that the functions of Haida classifiers can be roughly divided into static and dynamic in terms of the degree of dependence on the contexts in which they occur. The former function relates to noun classification, in which classifiers refer to inherent properties of the syntactically associated noun, whereas in the latter function, classifiers denote the temporal state of the noun referent or the state or manner of an action to add some meaning to the verbal root. Thus, Haida classifiers can be considered distinctive in that they cover a wide range of functions, from typical noun classifications to various other kinds of functions.
