Answer:
Possessive case of a plural noun ending in -s:
- I didn't have the time to wash the girls' dresses.
Possessive case of a plural noun not ending in -s:
- People's manners have greatly improved after the workshop on empathy.
Explanation:
The possessive case, also known as the genitive case, usually consists in the addition of 's to the ending of a noun to indicate that that noun is the possessor of something. For example: Sheila's books. / Erica's mother. / John's letters.
<u>When the noun already ends in -s in its plural form, all we need to do is add the apostrophe to indicate the possessive case:</u>
- I didn't have the time to wash the girls' dresses.
<u>When the noun has a plural form that does not end in -s, we need to add 's just like we would to its singular form:</u>
- People's manners have greatly improved after the workshop on empathy.
