The monkey in plural form is monkeys—add s because the y follows a vowel.
If you’ve ever typed “monkies” and felt unsure, you’re not alone. English has a real pattern for words that end in -y, and “monkey” sits in the easy lane.
This page gives the spelling, the rule behind it, and a set of quick checks you can use in essays, worksheets, captions, and class notes.
Fast Reference Table For -Y Plurals
| Singular | Plural | Rule Note |
|---|---|---|
| monkey | monkeys | Vowel + y → add s |
| boy | boys | Vowel + y → add s |
| toy | toys | Vowel + y → add s |
| donkey | donkeys | Vowel + y → add s |

Monkey In Plural Form Rules For Clear Writing
Write it as monkeys. One monkey, two monkeys. That’s it.
Spelling guides and dictionaries list “monkeys” as the plural form, with no alternate spelling for standard English. You can see it on the Merriam-Webster entry for monkey.
Why “Monkies” Looks Tempting
A lot of students learn a rule like “change y to ies,” and it sticks. The catch is the letter right before the y.
In “monkey,” the letter before the y is e, a vowel. When a noun ends with a vowel + y, you keep the y and add s.
Plural Of Monkey In Notes, Labels, And Titles
If you’re writing quickly, the safest move is to do a one-second scan: check the letter before the y.
Step 1: Check The Letter Before Y
- If it’s a vowel (a, e, i, o, u), add s: monkey → monkeys.
- If it’s a consonant, change y to ies: baby → babies.
Step 2: Watch For Names
Proper names are a special case. Even when a name ends in consonant + y, style guides usually add s for the plural: the Kennedys, the Murphys, the Bradys.
That rule helps you avoid stray apostrophes in family names on signs, shirts, and invitations.
The -Y Ending Pattern In Plain Words
Here’s the whole pattern without jargon:
Vowel + Y: Add S
These words keep the y and take an s: monkey/monkeys, boy/boys, toy/toys, alley/alleys, chimney/chimneys.
Try saying them out loud. The vowel sound before the y stays smooth, so English keeps the spelling simple.
Consonant + Y: Switch To Ies
These switch y to ies: baby/babies, city/cities, story/stories, cherry/cherries, duty/duties.
The spelling change keeps the plural ending readable and consistent across lots of words.
Monkeys, Monkey’s, And Monkeys’ Are Different
This is where many writing mistakes happen. A plural is about number. An apostrophe is about ownership or missing letters.
Plural: No Apostrophe
monkeys means more than one monkey.
- We watched three monkeys climb the rope.
- The monkeys shared a pile of fruit.
Singular Possessive: One Owner
monkey’s means something belongs to one monkey.
- The monkey’s tail was curled.
- I cleaned the monkey’s enclosure sign.
Plural Possessive: Many Owners
monkeys’ means something belongs to more than one monkey.
- The monkeys’ habitat was cleaned at noon.
- The monkeys’ calls echoed through the trees.
Using “Monkeys” Smoothly In Sentences
Once you have the spelling, the next step is making it flow in real lines of writing. Here are patterns that work in school and daily writing.
Counted Nouns With Numbers
- Two monkeys sat on the fence.
- Seven monkeys moved as a group.
- Dozens of monkeys live in the reserve.
With Quantifiers
- Many monkeys sleep in the shade at midday.
- Several monkeys were grooming each other.
- A few monkeys stayed near the water.
With Descriptions
- Young monkeys learn by watching older ones.
- Playful monkeys grabbed the hanging toy.
- Curious monkeys reached for the bright ribbon.
If you want another trusted reference, the Oxford Learner’s Dictionaries entry for monkey also shows the standard plural form.
Monkeys In General Statements And Group Names
Sometimes you use a plural even without a number. That’s common in school writing when you’re naming a whole group.
- Monkeys are mammals. (a general statement about the group)
- Monkeys live in many regions. (the subject is the group, not one animal)
- Monkeys in this exhibit are active in the morning. (the subject is the animals in a set place)
In those lines, you’re not counting. You’re naming the category, so the plural fits.
Monkeys In Compound Nouns And Fixed Phrases
English also uses “monkey” inside longer noun phrases. The plural usually goes on the main noun, not on each word.
When “Monkey” Is The First Word
If “monkey” is acting like an adjective in front of another noun, the second noun usually carries the plural ending.
- one monkey bar → two monkey bars
- one monkey wrench → two monkey wrenches
- one monkey cage sign → two monkey cage signs
You’ll still see “monkeys” when the animals themselves are the main noun: “two monkeys on the bars.”
When “Monkey” Is The Main Noun
When the animal is the core noun, pluralize it in the normal way.
- one monkey in the photo → monkeys in the photo
- a study of monkey behavior → studies of monkeys
- the sound of a monkey call → the sound of monkeys’ calls
Capitalization And Plurals In Headings
Headings can make spelling feel odd because they often drop articles like “a” and “the.” The plural rule doesn’t change.
Good: “Monkeys At The Zoo” and “Monkeys In Fiction.” Not: “Monkies At The Zoo.”
If your assignment prompt is the phrase “monkey in plural form,” treat it as a spelling task, not a style task. The answer stays the same in a title, a caption, or a sentence.
Short Editing Drill
Try this quick drill when you’re proofreading. It catches most slips in under a minute.
- Circle each apostrophe in your draft.
- Ask: is it showing ownership, or did it sneak in as a plural?
- Scan for words ending in y. Check the letter right before y.
- Fix only what the sentence asks for: plural, singular possessive, or plural possessive.
Edit This Paragraph
Draft with errors: “The monkies were loud. The monkey’s climbed the rope. We recorded the monkeys call.”
Clean version: “The monkeys were loud. The monkeys climbed the rope. We recorded the monkeys’ call.”
The first change fixes the vowel + y plural. The second removes an apostrophe that was used as a plural. The third adds an apostrophe because the call belongs to the group.
Common Errors And Quick Fixes
Most mistakes come from one of three spots: the -y rule, the apostrophe, or a spellchecker that guesses wrong.
Error 1: Writing “Monkies”
Fix: change it to monkeys. The vowel + y pattern needs only an s.
Error 2: Using An Apostrophe For A Plural
Fix: remove the apostrophe. “Monkey’s” is ownership, not a plain plural.
Right: “The monkeys are loud.” Wrong: “The monkey’s are loud.”
Error 3: Mixing Plural And Possessive
Fix: decide what you mean first.
- More than one animal → monkeys.
- One animal owns something → monkey’s.
- Many animals own something → monkeys’.
Error 4: Pluralizing In Parentheses
When you write a form like monkey(s), it works for quick notes. In formal writing, pick one form and write it out. It reads cleaner and avoids confusion in graded work.
Proofreading Table For Monkey Plurals And Apostrophes
| What You See | What It Means | Fix |
|---|---|---|
| monkies | Misspelling of the plural | Change to monkeys |
| monkey’s (plural meaning) | Apostrophe used as plural | Remove apostrophe: monkeys |
| monkeys (ownership meaning) | Plural used where ownership is meant | Add apostrophe: monkeys’ |
| monkeys’ (one owner meaning) | Plural possessive used for one | Use monkey’s |
| monkeys’s | Double s after plural | Use monkeys’ |
| the Monkey’s (family sign) | Name plural mistaken for possessive | Use the Monkeys |
| monkey (two animals) | Singular used for plural count | Use monkeys |
| monkeys (one animal) | Plural used for one count | Use monkey |
Spellcheck And Dictionary Checks
Autocorrect is helpful, but it can nudge you into the wrong apostrophe. If you type “monkeys” and a phone suggests “monkey’s,” pause and pick the form that matches your sentence.
A quick way to verify the spelling is to check a dictionary entry. If the entry lists “plural monkeys,” you’ve got the standard plural. If your keyboard keeps pushing “monkies,” add “monkeys” to your personal dictionary so it stops nagging you.
Fast Tests That Catch Most Slips
- Number test: can you place a number in front? “two ___” should read “two monkeys.”
- Ownership test: can you replace it with “belonging to”? If yes, you need an apostrophe.
- Swap test: trade the word for “boys.” If “boys” works, “monkeys” will work too.
Those checks feel simple, and that’s the point. You want a routine you’ll actually use while editing.
Mini Lesson You Can Teach Or Self-Check

Use A Pair To Lock It In
Match “monkey” with another vowel + y word you already trust, like “boy.” If you can write boys without hesitation, you can write monkeys the same way.
