Acrosst, instead of across, is one of the great American variants — one of the great American pronunciations. No one writes acrosst; but plenty say it. I was just watching that ad by Senator Jon Tester, the Montana Democrat — the ad in which he essentially campaigns against Obama, a president of his own party. You’ll find it on our homepage. And the tagline is: “Look acrosst our state. I do what’s best for Montana, always.”
And all acrosst my state, Michigan, you’ll hear the word heighth — not height, but heighth. Goes with length, depth, and width. I’d blush to tell you how old I was when I discovered that height had no “h” on the end . . .
