Have you ever typed “monkies” and stopped for a moment, wondering if it should actually be “monkeys”? You are not alone—this is one of the most common spelling mistakes in English.
At first glance, “monkies” may look correct because many words ending in “y” change to “ies” in plural form, such as city → cities and baby → babies. So why does monkey break this rule?
The answer lies in English pluralization patterns and pronunciation-based spelling rules. Understanding this difference not only clears confusion but also improves your grammar accuracy in emails, exams, academic writing, and everyday communication.
In this guide, you’ll learn the correct plural form of monkey, why this mistake happens, and an easy trick to remember it forever.

Pronunciation of Monkies or Monkeys
The word monkeys is pronounced:
MUN-keez
Phonetic spelling:
/ˈmʌŋ.kiːz/
How It Sounds
- Monkey = MUN-kee
- Monkeys = MUN-keez
Interestingly, both monkeys and the misspelling monkies would sound exactly the same when spoken. This is one reason people become confused when writing.
Spoken Examples
- The monkeys live in tropical forests.
- Spider monkeys are known for their long tails.
- Capuchin monkeys are intelligent primates.
Because pronunciation offers no clue about spelling, writers must rely on grammar rules.
Why People Confuse Monkies or Monkeys
The confusion comes from a common English spelling pattern.
Many words ending in y change to ies when pluralized:
- Baby → Babies
- City → Cities
- Lady → Ladies
- Puppy → Puppies
- Family → Families
People naturally assume:
- Monkey → Monkies
However, this assumption is incorrect.
The Real Rule
When a noun ends in:
Vowel + Y
Simply add S.
Examples:
| Singular | Plural |
|---|---|
| Monkey | Monkeys |
| Donkey | Donkeys |
| Turkey | Turkeys |
| Key | Keys |
| Toy | Toys |
Since monkey ends with ey (a vowel + y), the correct plural is monkeys.
Easy Trick to Remember Monkies or Monkeys
A simple memory trick can help you remember the correct spelling forever.
The Vowel Trick
Look at the letters before Y.
Monkey = E + Y
Since E is a vowel:
Add only S.
Monkey → Monkeys
Quick Formula
- Vowel + Y = Add S
- Consonant + Y = Change Y to IES
Examples:
| Pattern | Example |
|---|---|
| Vowel + Y | Monkey → Monkeys |
| Vowel + Y | Donkey → Donkeys |
| Consonant + Y | Baby → Babies |
| Consonant + Y | City → Cities |
Memory Sentence
“Monkeys keep the Y because a vowel stands nearby.”
This simple phrase makes the rule easy to remember.
The Origin of Monkies or Monkeys
The word monkey has an interesting history.
Origin of Monkey
The exact origin remains uncertain, but linguists trace the word to Middle English. The name may have originated from a character called Moneke found in medieval European stories.
Over time, monkey became the standard English word for certain types of primates.
Why the Plural Is Monkeys
English morphology follows specific pluralization patterns.
Since monkey ends in:
- vowel + y
The language keeps the y and adds s.
This rule also applies to:
- key → keys
- toy → toys
- valley → valleys
- journey → journeys
- donkey → donkeys
The spelling monkies developed because people incorrectly applied the baby → babies rule to the word monkey.
