I just discovered that the official Scrabble dictionary is online. Annoying for its acceptance of words like “ar,” the spelling of the letter ‘R,’ but diehard Scrabble players do seem to like it (snobbish comment: Kiara and I prefer to play with the OED as our dictionary, just because we have it). And for those games that I used to play with two sets of tiles so the board was nearly full, every little two-letter word I can muster came in handy.
