Amount is the correct spelling. Ammount is a misspelling — it is not an accepted variant in any form of English.
If you have been writing ammount, you are not alone. The double-m version has an oddly logical feel to it, which is exactly why people get tripped up.
Why Does “Ammount” Look So Natural?
English has plenty of words where doubling a consonant is the right move. Think of accommodate, announce, attempt, or abbreviate. When a prefix ending in a consonant attaches to a root starting with the same consonant, doubling happens naturally.
Amount comes from the Old French amont, meaning “upward” or “uphill” — literally “to the mountain” (a + mont). When it passed into Middle English, it carried that single m with it, and the spelling has stayed that way ever since. There is no prefix-plus-root doubling happening here, so there is no reason for two m’s.
The word simply never needed them.
What Does “Amount” Mean?
Amount refers to a quantity or total of something — how much of something there is.
It functions as both a noun and a verb.
As a noun:
- A large amount of rain fell overnight.
- The total amount was higher than expected.
- She saved a small amount each month.
As a verb (usually followed by to):
- The repairs amount to more than the car is worth.
- His excuses amount to nothing.
- The charges amount to a serious offense.
Amount vs. Number: A Useful Distinction
Since you are already thinking about how to use amount correctly, one more distinction is worth knowing.
Use amount with things you cannot count individually — things measured in bulk or mass:
- amount of water, amount of time, amount of effort, amount of money
Use number with things you can count as individual units:
- number of people, number of cars, number of mistakes
This distinction is standard in formal and careful writing. In everyday speech, people often use amount for both, but in professional or academic contexts, keeping them separate is the cleaner choice.
- ✗ A large amount of students attended.
- ✓ A large number of students attended.
- ✓ A large amount of homework was assigned.
Quick Spelling Check
If you ever second-guess yourself mid-sentence, the fix is simple: one m, not two.
a-m-o-u-n-t
Think of mount sitting inside the word — as in a mountain. One m at the start, and the rest follows.
The bottom line: Write amount every time. Ammount is never correct in any context, dialect, or style of English. The word traces back to a French root with a single m, and that is how it has been spelled in English for centuries.
