Explanation:
In English, there is one definite article and two indefinite articles.
The definite article "the" can be used with both singular and plural nouns. It is used when we refer to something or someone specific. For instance, when we say "I was rearranging the bookshelf," we convey that it was a specific bookshelf. It may have been mentioned previously in the conversation, or it may simply be the only bookshelf I have at home.
The indefinite articles "a / an" can only be used with singular nouns. They refer to something or someone that is not specific. Depending on the context, however, they can also simply mean the same as "one" (a week ago). When we say "a quiet place to study," we mean any quiet place, not a specific one.
"A" is used before consonant sounds (a flower) and "an" is used before vowel sounds (an umbrella).
