A lexeme belongs to a particular Syntactic Category , has a particular Meaning ( Semantic Value ), and in inflecting languages, has a corresponding Inflectional Paradigm ; that is, a lexeme in many languages will have many different forms. For example, the lexeme for ''run'' has a present third person singular form ''runs'', a present non-third-singular form ''run'', a past form ''ran'', and a present Participle ''running''. The use of the forms of a lexeme is governed by rules of Grammar ; in the case of English verbs such as ''run'', these include subject-verb agreement and compound tense rules, which determine which form of a verb can be used in a given sentence. A Lexicon consists of lexemes. In many Formal theories of Language , lexemes have Subcategorization Frame s to account for the number and types of complements they occur within Sentences and other Syntactic Structures . The notion of a lexeme is very central to Morphology , and thus, many other notions can be defined in terms of it. For example, the difference between Inflection and Derivation can be stated in terms of lexemes:
