WebThe indefinite article ("a," "an") is only for singular nouns. It is not used for plural nouns. As the indefinite article specifies one thing (e.g., "a cup" means "one cup"), it is not used with non-countable nouns (e.g., "water," "air," "integrity"). For example: I need an air. Play me a music. Give me a heat.
