 This entry uses “natural language ontology” as the term for the discipline and “the ontology of natural language” as a term for its subject matter. The more accurate term for the subject matter of natural language ontology would actually be “the ontologies of natural languages”, since natural languages may, in principle, reflect different ontologies and even the same language (or idiolect) might reflect different ontologies. For most of the entry, this is simplified by talking about the ontology of natural language, addressing the issue of different ontologies only in  Section 4.  This is justified by the fact that philosophers practicing natural language ontology generally presuppose that there is a single ontology shared by natural languages, as do, to a great extent at least, semanticists.
