Faithful correspondent Jeff wrote me about words that have confused him in the past. One of them was the distinction between “gray” and “grey.” If you are American, chances are overwhelming that you spell that color with an A. But did you know that the rest of the English-speaking world spells it with an E? If you decide you like the E-variant better for the color, go ahead and use it; you won’t be wrong. Just be consistent in any one document.
Oddly enough, even though in the United States we spell “gray” with an A, as we do with “graybeard,” “gray-haired,” “gray matter,” “gray wolf” and “gray market,” we spell “greyhound” with an E. That’s a word you can’t spell with an A. Go figure.
