Is the plural of monkey written as monkeys or monkies? This is a common spelling question because many English words ending in -y change to -ies when they become plural. However, monkey follows a different rule.
The correct plural form is monkeys, while monkies is incorrect in standard English. This guide explains why, how the plural rule works, and how to use the word correctly in everyday writing.
Monkeys or Monkies: Quick Answer
The correct spelling is:
✅ Monkeys
❌ Monkies
The word monkeys is the plural form of monkey.
| Singular | Plural | Correct? |
|---|---|---|
| Monkey | Monkeys | ✅ Yes |
| Monkey | Monkies | ❌ No |
Quick rule: Words ending in -y only change to -ies when the letter before y is a consonant. Since monkey ends with -ey and the letter before y is a vowel (e), it simply takes -s.
Why Is Monkeys Correct?
The spelling monkeys follows the standard English pluralization rule.
The word monkey ends with:
e + y
Because the letter before y is a vowel, the y stays unchanged when adding -s.
Examples:
- Monkey → Monkeys
- Donkey → Donkeys
- Key → Keys
- Boy → Boys
- Toy → Toys
The spelling does not change because these words already have a vowel sound before the final y.
Plural Rule for Words Ending in Y
Many learners remember a simple rule:
Change y to ies when making a plural.
But this rule has an important condition.
When to use -ies
If a word ends with a consonant + y, replace y with ies.
Examples:
| Singular | Plural |
|---|---|
| Baby | Babies |
| City | Cities |
| Story | Stories |
| Family | Families |
| Country | Countries |
In these words, the letter before y is a consonant.
When to keep the Y and add -s
If a word ends with a vowel + y, simply add -s.
Examples:
| Singular | Plural |
|---|---|
| Monkey | Monkeys |
| Donkey | Donkeys |
| Key | Keys |
| Toy | Toys |
| Day | Days |
Since monkey has e before y, the plural is monkeys.
