Where the Spellings Come From

The difference follows a common spelling pattern between American and British English.

American English often keeps a single l when adding endings to verbs ending in l if the final syllable is not stressed.

Examples include:

• traveled
• canceled
• fueled
• spiraled

British English commonly doubles the l before adding endings.

Examples include:

• travelled
• cancelled
• fuelled
• spiralled

Neither system is more correct than the other. They simply follow different spelling conventions.

Why People Get Confused

Many writers read content from both American and British sources without realizing the spelling rules differ.

Confusion also happens because:

• Spell checkers follow regional language settings.
• International companies publish content in different English varieties.
• Books and websites use different editorial style guides.
• Both spellings appear in dictionaries.

As a result, people often assume one spelling must be incorrect, even though both are accepted.

What Dictionaries Recommend

Major dictionaries recognize both spellings.

Most dictionaries list:

• Spiraled as the standard American English spelling.
• Spiralled as the standard British English spelling.

This means your choice should depend on your intended audience rather than on dictionary approval.

Real Life Examples Of Spiraled

American English

• The bird spiraled downward before landing.
• Prices spiraled out of control.
• The football spiraled through the air.

British English

• The bird spiralled downward before landing.
• Costs spiralled during the crisis.
• The smoke spiralled above the chimney.

Each sentence is correct within its respective variety of English.

Common Mistakes

One common mistake is mixing both spellings in the same document.

Incorrect:

• The plane spiraled toward the ground before it spiralled away.

Correct for American English:

• The plane spiraled toward the ground before it spiraled away.

Correct for British English:

• The plane spiralled toward the ground before it spiralled away.

Another mistake is assuming one spelling is wrong simply because it looks unfamiliar. In reality, both are standard spellings.

Easy Memory Trick

Remember the audience, not just the word.

• America prefers one L in spiraled.
• Britain usually doubles the L in spiralled.

If you’re writing for readers in the United States, choose spiraled. If you’re writing for readers in the United Kingdom, choose spiralled.

Professional Writing Recommendation

For the clearest and most polished writing:

• Use spiraled for American websites, schools, businesses, and publications.
• Use spiralled for British publishers, universities, government documents, and UK-based audiences.
• If your organization follows a specific style guide, always follow that guide.
• Stay consistent throughout the document instead of switching spellings.

Consistency is more important than choosing one regional spelling over the other.
