This one’s confusing, isn’t it? There’s the dog, greyhound. There’s Earl Grey tea. Of course, there’s 50 Shades of Gray. So, which is it? Is it spelled with an A or an E? he answer is: Yes. In almost all cases, either is acceptable. The difference is whether you’re in America or England. In America, the color is spelled gray. In England, it’s grey. That makes it easy to remember which is which, too. A for America, E for England.
