Two letter words acceptable in Scrabble

Please note that this list is mainly guesswork and memory. If you have a list of Scrabble words and see a word placed on here which isn't on here I suggest you remove it. Any word with a star is only allowed if abbreviations are allowed (words like ok, sp and tv don't count as abbreviations, words marked with a $ only count if plurals are allowed).
