Nouns

The definition of nouns on the top of this page is thus a formal definition.However, it has the disadvandage that it does not apply to nouns in all languages.There are also several attempts of defining nouns in terms of their semantic properties.The existence of such general nouns shows us that nouns are organized in taxonomic hierarchies.So the definition is not particularly helpful in distinguishing nouns from other parts of speech.Another semantic definition of nouns is that they are prototypically referential.[4] That definition is also not very helpful in distinguishing actual nouns from verbs.The British logician Peter Thomas Geach proposed a very subtle semantic definition of nouns.Proper nouns (also called proper names) are the names of unique entities.For example, Janet, Jupiter and Germany are proper nouns.
