Why Are There Two Spellings?

British English: Grey

In the United Kingdom, grey remains the standard spelling. You’ll find it in British dictionaries such as the Oxford English Dictionary and Cambridge Dictionary, as well as in UK newspapers, books, and government publications.

Both spellings have existed for centuries. Over time, each region settled on its preferred version, much like color/colour and center/centre.

For example:
