Monkeys

The plural form of “monkey” is where most people get confused. Many people expect the plural form to be “monkies,” but this is incorrect.

English has many rules for forming plurals, and “monkey” actually follows the standard rules. It’s true that if a word ends with “y,” the standard way to pluralize it is to replace the “y” with “ies.” However, if a word ends with “[vowel] y” you pluralize it by adding an “s” to the end.

Because “monkey” ends with “ey,” you make it plural by adding an “s.” There are a lot of other words where we can see this rule in action.

Incorrect:

  • Monkies
  • Donkies
  • Kies

Correct:

  • Monkeys
  • Donkeys
  • Keys

Keep in mind that “monkeys” is not possessive. It’s simply referring to more than one monkey. Here are some examples of how you might use “monkeys:”

  • There are 20 monkeys are the zoo.
  • How many monkeys are jumping on the bed?
  • My nephew loves monkeys!

Monkey’s

“Monkey’s” is the singular possessive form of “monkey.” Singular possessive nouns are extremely straightforward. If a noun owns something or possesses a trait, you show that relationship by adding an “s” with an apostrophe before it.

If you want to say a car belongs to a single monkey, you’d say: “That is the monkey’s car.”

Here are some more examples:

  • The monkey’s best friend is a cat.
  • His monkey’s favorite color is purple.
  • Have you seen my monkey’s blanket?
  • The monkey’s bad attitude earn him a punishment.

Monkeys’

“Monkeys'” is the plural possessive form of “monkey.” Plural possessive nouns can be a little bit tricky, but “monkey” follows the standard rule.

If there is more than one monkey and they collectively own something or possess a trait, you show that relationship by adding an “s” with an apostrophe after it.

You do not add a second “s” after the apostrophe. “Monkeys’s” is never correct.

If you want to say a car belongs to a group of monkeys, you’d say: “That is the monkeys’ car.”

Here are some more examples:

  • The monkeys’ favorite toys are all broken.
  • The monkeys’ home tree was knocked down in the storm.
  • The monkeys’ rambunctious behavior attracts many visitors to the zoo.
