A noun that can be preceded by the definite article and that represents one or all of the members of a class. As a general rule, a common noun does not begin with a capital letter unless it appears at the start of a sentence. Common nouns can be subcategorized as count nouns and mass nouns. Semantically, common nouns can be classified as abstract nouns and concrete nouns. Contrast with proper noun.
