THE

"The" is a definite article in English used to specify a particular noun that both the speaker and listener are familiar with. It indicates that the speaker refers to a specific object or person known in the context, rather than any general or unknown one. For example, saying "the book" points to a specific book that both parties recognize, unlike "a book," which could refer to any book. "The" helps clarify exactly what is being talked about, making communication clearer and more precise.
