ABSTRACT
The general term ‘form class’ will be used to cover both lexical classes and phrasal classes. There are two important and closely related points about the constituent structure of form classes: the membership or the internal structure of the class and the distribution of the class in other constituents. Particular lexical classes can be associated with particular ‘grammatical categories’. Lexical classes contain words. Other form classes may contain not only single words, but also strings of words. This chapter focuses on widening of the data base that include sentences with a new lexical class. It describes the ways of using the general form class label together with the distributional environments in the place of a specific label that distinguishes intransitive verbs and transitive verbs. The chapter includes some exercises for identifying the lexical categories, phrasal nodes, branching nodes, and non-branching nodes.
