Hello, fellow fiction writers. If you’ve ever sent your manuscript to an editor across the pond, you might’ve gotten it back looking like it’s bleeding red ink. And no—it’s not because your writing’s terrible. It’s because American and British English have different spellings, word choices, and even meanings.
For fiction writers, this can be a sneaky source of confusion. Your story might be perfectly polished in Chicago style, but if you’re aiming for a U.K. audience, suddenly your “color” becomes “colour” and your “apartment” mysteriously turns into a “flat.”
Let’s unpack the most common differences, with a few anecdotes and examples along the way.

Readers notice details—and nothing pulls a U.K. reader out of a story faster than “gray sidewalks,” just as “neighbours with torches” can throw off U.S. readers. Knowing the spelling and word differences between American and British English keeps your fiction consistent and your readers happy.
