Have you seen both spiralling and spiraling online and wondered which one is correct? You’re not alone. Many writers, students, and professionals search for “spiralling or spiraling”
because the two spellings look almost identical but appear in different places. Add common typos like “spiralingf”, and the confusion grows even more.
This spelling question often comes up in emails, academic writing, news articles, and SEO content. People want to sound professional, avoid mistakes, and choose the spelling their audience expects. The problem is that both spellings are correct—but not always interchangeable.
The confusion comes from differences between British English and American English. Each follows its own spelling rules, especially for verbs ending in -ing. If you use the wrong version,
your writing may look inconsistent or poorly edited, even if the meaning is clear.
This guide clears everything up. You’ll get a quick answer, learn where the words come from, see real examples, and know exactly which spelling to use based on your audience.
Spiralling or Spiraling – Quick Answer
Both spiralling and spiraling are correct spellings.
- Spiralling → British English
Example: The costs are spiralling out of control. - Spiraling → American English
Example: The prices are spiraling downward.
The meaning is the same in both cases. Only the spelling changes based on regional English rules.
The Origin of Spiralling or Spiraling
The word comes from the noun “spiral,” which entered English in the late 1500s from Latin spiralis, meaning “winding” or “coiled.”
When English developed different standards in the UK and the US, spelling rules changed. British English often keeps doubled consonants when adding -ing, while American English often simplifies spelling.
That’s why:
- Spiral + ing becomes spiralling in British English
- Spiral + ing becomes spiraling in American English
The difference is historical, not grammatical.
