IRIS is itself a valid word in both Scrabble and Words With Friends, worth 4 points and 4 respectively on plain squares. Rearranged and shortened, the same 4 letters make 5 words in total, from 4 letters down to two. No other word uses all 4 letters, which makes it a safe rack to hold. The highest scoring option is IRIS at 4 points in Scrabble. (Class. Myth.) The goddess of the rainbow, and swift-footed messenger of the gods.
