Labour or Labor: Which Spelling Is Correct?

🕓 Last updated on October 10, 2026

You are typing a message. You stop. Is it “labour” or “labor”? You look at the screen. Both look right. Both look wrong.

You are not alone. Millions of people search “labour or labor” every year. Students want to pass an exam. Workers write emails to bosses. Bloggers publish to readers around the world. Everyone wants to look professional.

The good news is simple. Both spellings are correct. They are not two different words. They are two spellings of the same word. One is used in British English. The other is used in American English.

So why the mix-up? English has no single rulebook. Different countries made different choices long ago. Today, we live with both.

This guide clears up the confusion. You will get a quick answer first. Then you will learn where the word came from. You will see a side-by-side table, real examples, common mistakes, and answers to common questions. By the end, you will know exactly which spelling to pick.

Labour or Labor   Quick Answer

Both are correct. Use “labor” in the United States. Use “labour” in the UK, Canada, Australia, and most other English-speaking countries.

That is the whole rule. Here are some examples:

• US: “The Department of Labor posted new job numbers.”
• UK: “The Labour Party won the vote.”
• Canada: “Many families enjoy the Labour Day long weekend.”
• US: “Hard labor built the railroads.”
• UK: “It was a labour of love.”

The meaning does not change. The word means work, effort, or workers as a group. It can also mean the process of giving birth.

The Origin of Labour or Labor

The word comes from Latin. The Latin word labor meant work, toil, or hard effort.

The word then moved into Old French as labour or labeur. After the Norman conquest in 1066, French words poured into English. “Labour” came with them. It was in English by the 1300s.

For a long time, spelling was loose. People spelled words as they liked. Many used “labour.” Some used “labor.” Nobody called it an error.

Then came Noah Webster. He was an American writer who made a famous dictionary. In the early 1800s, he wanted American English to look simple and different from British English. He cut extra letters. He dropped the “u” in words like colour, honour, and labour.

His 1828 dictionary spread these spellings across the United States. Britain kept the older French-style “-our” spelling.

British English vs American English Spelling

Many words follow the same pattern. British English keeps “-our.” American English uses “-or.”

Meaning	British English	American English
Work or effort	labour	labor
A person who works	labourer	laborer
Hard to do	laborious	laborious
Worked hard	laboured	labored
Shade of paint	colour	color
Respect	honour	honor
Neighbor	neighbour	neighbor
Favorite	favourite	favorite

Two simple rules:

1. Noun and verb forms: The UK keeps the “u” (labour, laboured, labouring). The US drops it (labor, labored, laboring).
2. “Laborious” is the same in both. Both countries drop the “u” in this word. Many people forget this..

Which Spelling Should You Use?

Think about your reader. Then pick.

Writing for the United States?
Use labor. This includes Labor Day, Department of Labor, and labor laws.

Writing for the UK, Ireland, or Commonwealth countries?
Use labour. This includes Canada, India, South Africa, Nigeria, Kenya, and New Zealand.

Writing for Australia?
Use labour in general writing. But note this: the Australian Labor Party uses “Labor” in its name. Names are special. Always copy the official spelling.

Writing for a global audience?
Pick one and stay consistent. Many global websites use American English because most search traffic comes from the US. But if most of your readers are in the UK or Canada, use “labour.”

Quick rule for names: Official names never change. It is the Labour Party in the UK. It is the U.S. Department of Labor. It is the International Labour Organization. Copy the name exactly.

Tip: Set your spell checker to the right language. In Word or Google Docs, choose English (US) or English (UK).

Conclusion

Labour or labor? Here is what to remember.

Both spellings are correct. They mean the same thing. The difference is place. Americans write “labor.” The British, Canadians, and many others write “labour.”

The split started long ago. The word came from Latin and French. Then Noah Webster dropped the “u” in his American dictionary. Britain kept it.

Now the rules are easy. Know your reader. If they live in the US, use “labor.” If they live in the UK, Canada, or most Commonwealth countries, use “labour.” If your audience is global, pick one and stay consistent.

Watch for the special cases. Official names never change. It is the Labour Party in the UK and the Labor Party in Australia. “Laborious” never has a “u.” And do not mix spellings in one text.

One last tip: set your spell checker to the right English. It will catch mistakes for you.

Spelling may seem small. But the right choice shows care. It tells your reader you know them. Choose the spelling that fits your audience, and write with confidence.
