Have you ever typed “monkeys or monkies” and stopped to wonder which spelling is correct? You are not alone. This is a common spelling mistake because the word monkey ends in -ey, and English has several plural spelling patterns that can be confusing.
The good news is simple: monkeys is the correct plural spelling. Monkies is incorrect in standard English.
The confusion usually comes from words such as baby, city, and puppy. When these words end in a consonant followed by y, the y changes to ies in the plural: baby → babies and city → cities. Because monkey ends in y, some writers assume the same rule applies.
But monkey is different. The letter before y is a vowel, e, so the normal plural form simply adds s: monkey → monkeys.
This guide explains the difference between monkeys or monkies, shows the spelling rule, gives everyday examples, and answers common questions.

The Origin of Monkeys or Monkies
The word monkey has an interesting history. It appeared in English in the late Middle Ages, although its exact origin is uncertain. It may have developed from forms connected with older European words for monkeys or apes.
The plural is formed according to a common English spelling rule.
The singular word is:
monkey
It ends with -ey. When making the plural, English normally adds s:
monkey + s = monkeys
There is no need to change y to i.
This is different from words ending in a consonant + y.
For example:
- baby → babies
- city → cities
- country → countries
- puppy → puppies
The key difference is the letter immediately before y.
In monkey, the letter before y is e, a vowel. Therefore, the plural is monkeys.
