proper noun

Compare common noun.

Grammar note
Proper nouns are not normally preceded by an article or other limiting modifier, as any or some. Nor are they usually pluralized. But the language allows for exceptions. Proper nouns may occasionally have a definite article as part of the name, as in the case of some ships, organizations, and hotels, as The Titanic, The Humane Society, and The Plaza. An indefinite article is appropriate when you use a name as an exemplar: She looks like a young Elizabeth Taylor! And there is sometimes a reason for treating a name as if it were a generic: There are four Devons in my class. Proper nouns, usually capitalized in English, are arbitrary, in that a name can be given to someone or something without regard to any descriptive meaning the word or phrase may otherwise have.
