Question

Which of the following words is an indefinite article?

1)that
2)so
3) a
4)an
5)the

Answer 1

The word 'a' is an indefinite article used to indicate that a noun is not specific, making it the answer to the student's question.

Step-by-step explanation:

The word 'a' is an indefinite article. Indefinite articles are used before nouns to indicate that the noun is not specific. The articles 'a' and 'an' signal that the noun modified is indefinite, referring to any member of a group. For example, 'I would like an apple' does not refer to any specific apple; just any apple will do. Contrast this with 'the', which is a definite article and refers to a specific item.
