When can the word the be used?

Answer 1

The word "the" in English is an article (sometimes called a determiner), the definite article.

• The definite article is placed before a noun to indicate that the noun that follows is a specific person or thing.

The indefinite articles are "a" and "an", used to indicate that the noun that follows is not a specific person or thing.

• The article "a" is used before a word beginning with a consonant sound;
• The article "an" is used before a word beginning with a vowel sound.
