<P> A proper noun is a noun that in its primary application refers to a unique entity , such as London , Jupiter , Sarah , or Microsoft , as distinguished from a common noun , which usually refers to a class of entities ( city , planet , person , corporation ) , or non-unique instances of a specific class ( a city , another planet , these persons , our corporation ) . Some proper nouns occur in plural form ( optionally or exclusively ) , and then they refer to groups of entities considered as unique ( the Hendersons , the Everglades , the Azores , the Pleiades ) . Proper nouns can also occur in secondary applications , for example modifying nouns ( the Mozart experience ; his Azores adventure ) , or in the role of common nouns ( he 's no Pavarotti ; a few would - be Napoleons ) . The detailed definition of the term is problematic and to an extent governed by convention . </P>
