“Gray” and “grey” are two accepted spellings of the same word that describe the color between black and white. They carry identical meanings, but their usage differs based on regional English conventions. In modern writing, “gray” is standard in American English, while “grey” is more common in British English and other Commonwealth varieties.
Which Spelling Is Correct?
Both spellings are correct in English:
- Gray → preferred in American English
- Grey → preferred in British English and many international varieties
The difference is stylistic, not grammatical or semantic.
Why Are There Two Spellings?
The word originates from Old English grǣg, which evolved into different standardized forms as English spread across regions.
Over time:
- American English simplified and standardized spelling as “gray”
- British English retained “grey” as the traditional form
Both versions remained in use because English has no single global spelling authority.
