Both “spiralled” and “spiraled” are correct, but “spiralled” is mainly used in British English while “spiraled” is the standard spelling in American English. The difference comes from the way British and American English handle words ending in a consonant before the suffix -ed.
People often search for “spiralled or spiraled” because both forms appear in books, websites, news articles, and everyday writing. Seeing one spelling in British sources and another in American sources can make it difficult to know which version to use.
The two words have the same meaning. Both are the past tense and past participle of spiral, meaning to move or develop in a circular or winding way. The word can describe physical movement, such as a plane spiraling downward, or a situation that keeps getting worse or changing rapidly.
The main difference is regional style. British English usually doubles the final consonant before adding -ed, giving “spiralled.” American English usually keeps one “l,” giving “spiraled.”
Understanding this simple spelling rule can help you choose the right form for your audience and keep your writing consistent.

Definition and Meaning of Spiralled or Spiraled
Spiralled and spiraled are forms of the verb spiral.
To spiral means to move in a curved or circular path that gradually moves around a central point. The word can also describe something that develops rapidly, often in a particular direction.
Simple Meaning
In simple terms, spiralled or spiraled means:
Moved, changed, or developed in a spiral pattern.
For example:
The leaves spiralled through the air.
Here, the leaves moved in a curved, winding path.
The word can also describe a situation:
Costs spiraled after the project was delayed.
In this sentence, costs increased quickly.
Physical Movement
The word can describe actual movement through space.
The ball spiralled into the air.
The ball followed a curved or rotating path.
Rapid Change
The word can also describe a situation that changes quickly.
Her expenses spiraled out of control.
Here, the word does not describe physical circular movement. It describes a rapid increase.
Negative Development
“Spiral” is often used when something becomes progressively worse.
The argument spiralled into a serious dispute.
This means the situation developed quickly and became more serious.
Verb Forms
The basic forms include:
- Base form: spiral
- Past tense: spiralled : spiraled
- Past participle: spiralled : spiraled
- Present participle: spiralling : spiraling
The choice between the double l and single l depends mainly on the English variety being used.
The Origin of Spiralled or Spiraled
The word spiral comes from the idea of a spiral shape or movement. Its history is connected to words used to describe a winding or coiling form.
The spelling difference between spiralled and spiraled developed from broader differences between British and American spelling conventions.
British English often doubles a final consonant when adding a suffix in certain words. This gives forms such as:
- spiral → spiralled
- travel → travelled
- cancel → cancelled
American English often keeps one final consonant in these cases:
- spiral → spiraled
- travel → traveled
- cancel → canceled
This does not mean that one spelling is wrong. They reflect different standard spelling systems.
The difference became especially noticeable as American English developed its own spelling conventions. American dictionaries and style guides generally favored simpler spellings in many words, while British English retained forms with doubled consonants.
As a result, both spiralled and spiraled are now established forms, but their regional use differs.
British English vs American English Spelling
The main difference between spiralled and spiraled is regional spelling.
British English generally uses spiralled with a double l. American English generally uses spiraled with one l.
The pronunciation and meaning stay the same.
| Feature | British English | American English |
| Base verb | spiral | spiral |
| Past tense | spiralled | spiraled |
| Past participle | spiralled | spiraled |
| Present participle | spiralling | spiraling |
| Meaning | Same | Same |
| Example | Prices spiralled upward. | Prices spiraled upward. |
| Main spelling style | Double l | Single l |
British English
In British English, the standard forms are:
The costs spiralled higher than expected.
The situation spiralled out of control.
The same pattern appears in other British spellings:
- travelled
- cancelled
- labelled
- modelling
- controlled
This spelling style often keeps the final consonant doubled when a suffix is added.
American English
American English generally uses the single l form:
The costs spiraled higher than expected.
The situation spiraled out of control.
Similar American spellings include:
- traveled
- canceled
- labeled
- modeling
- controlled
The choice is therefore mainly a matter of regional spelling convention.
Why Is There One L in American English?
American English often simplifies some doubled-consonant spellings. This is especially noticeable in words ending in -el.
However, not every word follows the same pattern. Some words keep doubled consonants in American English too.
For this reason, it is better to learn the accepted spelling of each word rather than apply one rule to every situation.
Which Spelling Should You Use?
The right choice depends on your audience and the style of English you are using.
For American English

For example:
The company’s expenses spiraled after the unexpected delay.
This is the standard form for American writing.
