Question

How do you identify plural and possessive nouns??

Answer 1

 Making singular nouns possessive. Add an apostrophe + s to most singular nouns and to plural nouns that do not end in s. You'll use this rule the most, so pay particular attention to it. English has some words that are plural but do not add an 's'.

Answer 2

To make a singular noun possessive, add an apostrophe and an “s.” This applies to plural nouns that do not end with an “s”, like children - children's and men - men's. When making plural possessive nouns, add only an apostrophe if the noun ends with an “s”, like buses' and countries'.  HOPE IT HELPS
