playing a lot of scrabble -- our regular play includes a list of two-letter words on paper, in pencil, nearby to settle disputes (not visible during play). The arguments get heated ! .. (our list is smaller than the official list of two letter words, based on mutual agreement of real-world use). Personal opinion is that the official list is already too broad, and makes the play "muddy." Dictionary exploration is nerd…
No, this is against the rules. You know what we call a list of words? A dictionary. You aren't allowed to have those open until a word gets challenged. A decade ago I had all the two letter words in the Scrabble dictionary memorized, I doubt I'd still be able to spit them all out.
