* The labels Nominal and Verbal are used as approximate categories only. There is no universal rule that a particular feature can only occur with verbs or nominals (although language-specific rules may define such constraints). Even the boundary between lexical and inflectional features is sometimes blurred: for example, gender is a lexical feature of nouns but an inflectional feature of adjectives or verbs.
