Question

in what form should an article be written

Answer 1

Indefinite articles are the words 'a' and 'an.' Each of these articles is used to refer to a noun, but the noun being referred to is not a specific person, place, object, or idea. It can be any noun from a group of nouns. For example: a Mercedes from the car lot.
