Practice with plural nouns

Not sure exactly what you are asking. However, a plural noun is a word that indicates there is more than one person, animal place, thing, or idea. So when you talk about more than one of a person, animal, place, thing or idea (pretty much anything) then you are using plural nouns. When you write about more than one of anything, you basically use the same word and add an "s", "es", or "ies" to the end of the word. Hope that answers what you are looking for.
