A plural possessive noun is a plural noun that indicates ownership of something.
Example
The dog’s food is in the bag on the floor. (singular possessive: one dog)
The dogs’ food is in the bag on the floor. (plural possessive: multiple dogs)
In the two sentences, the nouns dog and dogs are neither the subjects nor the objects. Rather, both words are nouns that identify the owner of the subject (food).
The first sentence includes a singular possessive (dog’s): The food belongs to one dog. The second sentence tells us that the food belongs to more than one dog by means of a plural possessive noun, dogs’.
To make a plural possessive noun, first form the plural of the singular noun. Many singular nouns can be made plural by adding -s or -es to the end of the noun: string > strings, car > cars, church > churches, glass > glasses.
Some nouns are irregular, so they form the plural in ways other than by adding -s or -es: loaf > loaves, mouse > mice, man > men, foot > feet.
After you have formed the plural of the noun, add an apostrophe (‘) if the plural noun ends in -s or -es: strings’, cars’, churches’, loaves’. If the plural noun does not end in -s, add an apostrophe and an s: mice’s, men’s, feet’s.
Let’s look at more examples of both regular and irregular plural possessive nouns:
I really like the string’s sound on that guitar. (singular possessive)
I really like the strings’ sound on that guitar. (plural possessive)The glass’s fragments left a glittering trail on the floor. (singular possessive)
Have you seen the churches’ stained-glass windows?(plural possessive)Have you seen the church’s stained-glass windows? (singular possessive)
Have you seen the churches’ stained-glass windows?(plural possessive)What is the foot’s purpose for that table? (singular possessive)
What is the feet’s purpose for that table? (plural possessive)
Note that some irregular plural nouns are the same as their singular forms (e.g., aircraft, deer, sheep, furniture). In these cases, we would apply the same principles for forming the plural possessive for a noun that does not end in -s.
Examples
Both aircraft’s engines have been checked.
The three deer’s hoof tracks are all in the same spot.
The furniture’s prices appear on their tags.
Some animal nouns also might form the plural by either maintaining the singular or adding -s or -es: shrimp > shrimp or shrimps, fish > fish or fishes. Once again we would treat the plural possessive form according to the word’s ending as we’ve discussed:
You can put the shrimp’s tails in that bowl.
You can put the shrimps’ tails in that bowl.We could see the fish’s eyes as their school swam past us.
We could see the fishes’ eyes as their school swam past us.
If two or more nouns have ownership of another noun together, we would express that ownership by making only the last noun of the group possessive.
Jack, Jill, and Jerry’s water pail is at the top of the hill. (The pail belongs to all of them.)
The lawyers are reviewing the players and managers’ contract. (The contract belongs to the players and managers jointly.)
If two or more nouns each have their own separate possession of one or more nouns, we would make each noun of ownership possessive.
Jack’s, Jill’s, and Jerry’s water pails are at the top of the hill. (They all have their own pails.)
The lawyers are reviewing the players’ and managers’ contracts. (The players and managers have their own contracts.)
Some plural nouns are formed by making the first word in the phrase plural: sisters-in-law, passers-by, attorneys at large. In these cases, we would form the plural possessive by making the last word in the phrase possessive: sisters-in-law’s, passers-by’s, attorneys at large’s.
The sisters-in-law’s relationships with one another are healthy and strong.
The passers-by’s testimonies about the incident will be included in the investigation.

Merriam-Webster and OED write “passersby,” not “passers-by.”
Cambridge Dictionary and Collins both write “passers-by.” American Heritage allows for either spelling. It is a style choice.
1. My grandparent’s / grandparents’ house is on Lumley Road.
(Are both grandparent’s and grandparents’ correct in this sentence?)
2. A: My sneakers are old. I need new ones. What about these?
B: These sneakers are for women. The men’s / mens’ sneakers are over there.
(Is “men’s” an adjective in this sentence?)
If you are referring to one grandparent, write “grandparent’s house.” If more than one grandparent is living there, write “grandparents’ house.”
The sentences in your second example are grammatically correct.
The adjective “men’s” is correct.
“Car door handle“
Where should I put the s?
It depends on the accuracy of your intended meaning. If you write “car’s door handle,” it could be correct, but it could also technically suggest the car has one door handle. Most cars have more than one door and door handle, so if you write “car door’s handle,” you are identifying the handle on a particular car door among what could be, for example, four doors.
What about “the women’s song”?
If you are referring to more than one woman, the plural possessive “the women’s song” is grammatically correct. See our post The Most Common Punctuation Error of All.
When referring to a sports team enthusiast, such as a fan of the Dallas Cowboys, would I write:
Cowboys’ fan, Buckeyes’ fan, Warriors’ fan
or
Cowboys fan, Buckeyes fan, Warriors fan?
I can’t decide whether Buckeyes/Cowboys/Warriors is just an adjective or a possessive plural noun.
Thanks!
When referring to the fans, the team name is being used as an adjective to describe the word fans. Since the team does not own or possess the fans, an apostrophe is not used. See our post Apostrophes and False Possessives for more information.
What about “The Smiths’ kitchen” vs. “The Smith’s kitchen” (plural Smiths, ownership of singular kitchen).
If you are referring to more than one person whose last name is Smith, form the plural by adding an s, and put an apostrophe after the s. See our Rules for Apostrophes.
The Smiths’ kitchen
