Labour or Labor : Quick Guide for American English Writers(2026)

I remember the first time I wrote the word labour in an article, and something felt off. My spelling checker suddenly highlighted it and suggested labor instead. For a moment, I thought I had made a simple spelling mistake.

But when I looked at other websites, some were clearly using labour, while others used labor. That’s when I realized the confusion wasn’t just mine many writers face the same problem.

So I did what most of us do when we’re unsure: I started digging a little deeper. I checked grammar guides, looked at examples from different countries, and quickly discovered that the difference wasn’t about right or wrong. It was about where your audience is from.

In this guide, I’ll share exactly what I learned so you don’t have to spend time wondering which spelling to choose. By the end, you’ll clearly understand when to use labour and when labor is the better choice.

Labour or Labor – Quick Answer

Both labour and labor refer to work, effort, or the process of giving birth.

Labour – preferred in British English and Commonwealth countries.
Labor – preferred in American English.

Example:

UK: “The labour union negotiated better wages for its members.”
US: “The labor union negotiated better wages for its members.”

Both forms are correct; choose based on the region of your audience.

The Origin of Labour or Labor

The word comes from the Latin “labor,” meaning work or toil. Over time, English inherited both forms. British English kept the “ou” in words like labour, honour, and colour, following traditional spelling rules. American English simplified these words, dropping the “u” to form labor, honor, and color. This simplification helped standardize US English in the 19th century and is now widely used in American writing.
