Definite and Indefinite Articles Worksheet

  • Singular count nouns (nouns that can be counted) take either “a/an” (unspecified) or “the” (specified): “a” dog versus “the” dog.
  • Plural count nouns (nouns in their plural form) take either no article if a general remark is being made about the category or “the” if reference is made to a particular person or thing: “snakes” versus “the” snakes.
  • Non-count nouns (collective nouns) may be specified or unspecified. Use no article whenever they are unspecified and referred to generally; use “the” to specify a non-count noun: “time” versus “the” time.
