This chapter continues an examination of the structural features of the Dictionnaire’s LF by focusing on its inflectional categories and the means by which they are expressed. It begins with a brief survey of inflection in pidgins (Section 7.1) and the Romance lexifiers of LF (Section 7.2). The purpose of the survey is to map out the anticipated structural and typological limits for the inflectional categories of LF and their morphosyntactic expression. Section 7.3 looks at the inflection classes and inflectional categories of LF nominals and their exponence. Section 7.4 does the same for LF verbs. Section 7.5 looks at the expression of pronominal possessors and pronominal objects in the Dictionnaire’s LF. Whenever necessary, the Dictionnaire’s data is contrasted with Haedo’s (1612). Section 7.6 summarizes the conclusions.
