Bellys or bellies? If you are unsure how to spell the plural of belly, the answer is simple: bellies is correct.
The spelling bellys is incorrect in standard English.
The confusion comes from a common spelling rule involving nouns that end in -y. When a noun ends in a consonant + y, the y usually changes to i before the plural ending -es.
So:
belly → bellies
The same pattern appears in:
baby → babies
city → cities
family → families
story → stories
But this rule does not apply to every word ending in y. If the word ends in a vowel + y, the y stays:
boy → boys
toy → toys
key → keys
Understanding this small rule makes belly or bellies much easier to remember.
Quick Answer

✅ The babies had round bellies.

What Does Belly Mean?
Belly is a noun that usually refers to the front part of the human or animal body between the chest and the hips.
For example:
My belly feels full.
The baby has a round belly.
The word can also be used informally to mean the stomach or abdomen.
For animals, it can describe the underside of the body:
The dog rolled onto its belly.
Belly can also be used in a broader or figurative way.
For example:
The ship has a large belly.
The balloon’s belly expanded as it filled with air.
What Does Bellies Mean?
Bellies is simply the plural of belly.
It refers to more than one belly.
For example:
The children had full bellies after lunch.
The puppies slept on their bellies.
Several people rubbed their bellies after the meal.
The spelling changes because belly ends in consonant + y.
belly → bellies
Why Is “Bellys” Wrong?
The spelling bellys incorrectly applies the ordinary plural rule of simply adding -s.
A learner might think:
belly + s = bellys
But English has a special spelling pattern for many nouns ending in consonant + y.
The usual change is:
y → i + es
Therefore:
belly → bellies
Not:
❌ bellys
This is the same reason we write:
family → families
country → countries
lady → ladies
party → parties
The Y-to-IES Rule
Here is the main rule to remember:
When a singular noun ends in consonant + y, change the y to i and add -es.
Examples:
| Singular | Plural |
|---|---|
| belly | bellies |
| baby | babies |
| city | cities |
| family | families |
| country | countries |
| story | stories |
| party | parties |
| lady | ladies |
This rule explains why bellies is correct.
But Not Every Y Becomes I
There is an important exception.
If a noun ends in vowel + y, keep the y and simply add -s.
For example:
boy → boys
toy → toys
key → keys
day → days
monkey → monkeys
Compare:
belly → bellies
with:
boy → boys
Why?
Belly ends in:
l + y
The l is a consonant.
Boy ends in:
o + y
The o is a vowel.
This distinction is one of the most useful spelling rules for English plurals.

You can say:
a belly
one belly
two bellies
several bellies
When forming the plural, change -y to -ies.
Singular
The baby has a small belly.
Plural
The babies have small bellies.
The word itself does not become bellys.
Belly as a Verb
Belly can also function as a verb in certain contexts.
For example:
The boat bellied out in the middle.
It can also appear in informal expressions such as:
belly up
The spelling of the past tense is:
belly → bellied
Again, the y → i spelling pattern appears before -ed.
Belly as an Adjective or Modifier
Belly can appear in compound expressions and modifiers.
Examples include:
- belly button
- belly fat
- belly dance
- belly laugh
- belly ache
- belly flop
- belly rub
When used in these compounds, belly does not automatically become bellies.
For example:

Pluralization depends on the grammar of the entire expression.

Common Mistakes
Mistake 1: Writing “bellys”
❌ The babies have round bellys.
✅ The babies have round bellies.
Mistake 2: Forgetting the E in -ies
❌ bellis
❌ bellys
✅ bellies
Mistake 3: Using “bellies” for one belly
❌ My bellies hurts.
✅ My belly hurts.
Use belly for one and bellies for more than one.
Mistake 4: Applying the rule to every Y word
Not every word ending in y changes to -ies.
For example:
toy → toys
boy → boys
key → keys
So you must check whether the letter before y is a vowel or consonant.
