Question

Anil borrowed ___ story book for children from his neighbour​

Answer 1

Anil borrowed a story book for children from his neighbour.

• In English grammar, there are three articles -

1. A
2. An
3. The

• Now when the noun is singular, we use a or an article. The usage of a or an depends on the starting letter of the associated noun.
• Here, the associated singular noun is "story", which begins with "s". And, we know that, when the word starts with a consonant, generally the a article is used.

Articles:   

There are two kinds of articles in English grammar.      

1) Definite article (The):     

• The definite article "The" is used before a singular noun that is a specific or particular noun.

2) Indefinite article (A/An):      

• Article "A" is used before an unspecific singular noun that begins with a consonant sound.  

• Article "An" is used before an unspecific singular noun that begins with a vowel sound.
