ARTICLES
Reading edition
Use an article with every noun of a series unless the nouns are so closely related that one concept is implied. Say, The bread and jam was good, but The bread and the jam were good. Say, A horse and buggy, but A man and a woman.
Do not repeat an article before each adjective of a series when all modify the same noun. Say, A red, white and blue flag. If you mean three flags, say, A red, a white, and a blue flag.
Do not write a or an after sort of and kind of. Make it: He is the right sort of man for mayor.
The definite article is used too often when it might better be omitted, as in this sentence: The study of the dictionary is helpful. Write it: Study of the dictionary.
