Chapter 1-4-1: Definite Articles
The definite article “the” tells readers or listeners that its accompanying noun is identifiable; that is, the readers know exactly which specific noun the author is referring to. As long as the definite article is being used in this way to refer to things specifically, it can be used in front of every type of noun and noun phrase (singular count, plural count, and non-count nouns). For example:
