How do you indicate if a word is possessive when it is plural?

Answer 1

By adding an apostrophe to the end of the word.

If the word does not end with an 's' then add an apostrophe and then 's'.

For example:

• The girls' room. (word ends in an 's' so just an apostrophe is added)
• The men's room. (word does not end in an 's' so an apostrophe then 's' is added)

Answer 2

To indicate possession when a word is plural, you generally add an apostrophe after the "s" at the end of the word. For example, if you have "girls" as the plural form, the possessive form would be "girls'" (e.g., "the girls' toys"). However, if the plural word does not end in "s", you would add an apostrophe and then "s" to show possession (e.g., "the Children's Books" for the plural form of "child").
