English grammar rule Dt dt
To make it clear which noun you’re referring to, you can use an article. The is called a “definite article,” while A and an are indefinite articles. Use the definite article to point to a specific item, and an indefinite article to designate a nonspecific item. For example, if you want the red cookbook, say “Hand me the red cook book,” but if any cook book will do, you can say “Hand me a cook book.” Just remember that you can only use one article with the same noun.
