Authour vs Author- Spelling Made Simple

The Short Answer

Author is the only correct spelling. That's it. Full stop. Authour doesn't exist in any dictionary, anywhere.

Every major style guide—Chicago, AP, MLA—agrees. If you write "authour," you're simply wrong. No grey area. No debate.

Why People Misspell "Author"

The confusion comes from British English. Words like colour, honour, favour, and behaviour keep the "ou" spelling. Some assume "author" follows the same pattern.

It doesn't. The "ou" in British spellings comes from Old French, but "author" took a different path through Latin (auctor) into English. The "u" dropped off somewhere along the way, and it stayed gone.

Another reason: autocomplete and spell-check sometimes suggest "authour" in older dictionaries or poorly configured tools. Don't trust it.

British vs American Spelling

Notice: "author" stays the same in both variants. It never had a "u" to begin with in standard English.

The Etymology Doesn't Help (But It's Interesting)

The word comes from Latin auctor, meaning "originator" or "creator." The "c" became a "t" in Old French (auteur), which is where British English got its "-our" endings.

But when English borrowed "auteur," the spelling shifted again. By the 1600s, "author" was the standard form. The extra "u" was a historical dead end.

So while your instinct to add "u" makes sense for other words, it's wrong here. English spelling is arbitrary like that.

Here's how the correct spelling looks in real sentences:

Notice: no "u" anywhere. Not in "author," not in "author's," not in "authors."

Final Take

Stop second-guessing yourself. Author has no "u." It's one of the few words in English that looks simpler than you expect.

If you're writing for publication, academic work, or professional documents—always use "author." If someone edits your work and changes "author" to "authour," find a better editor.

Spell it right. Move on.
