 Natural language ontology is just at the initial stage of developing as a discipline of its own. The methodological issues surrounding it still await a serious discussion, such as the relation of the ontology reflected in language to different conceptions of reality and to ontologies tied to other representational or cognitive functions, the particular notion of implicit acceptance that the ontology of natural language involves, the core-periphery distinction, the ontological status associated with different semantic roles, the way ontological categories are reflected in natural language given recent theoretical syntactic and cross-linguistic research, and the different connections of the ontology of natural language to the functional and the lexical part of grammar.
