More than 100 two-letter words are acceptable in Scrabble 22 of the most unfamiliar and most bizarre of which are listed here. If you play the word DREAM directly beneath it, one letter below the other, then you’ll not only pick up points for using your D, R, E, A, and M, but you’ll also score for the words ED, AR, RE, TA, and HM that are formed between the two. So imagine, for instance, that your opponent has just played the word EARTH. But among competitive Scrabble players, two-letter words are a crafty means of boosting your score: Instead of linking one word perpendicularly to another, try playing one word directly on top of, alongside, or overlapping another on the board to form a chain of two-letter words between the two.
In a race to use up your final few tiles at the end of the game, low-scoring pairs like AD, AS, AN, and AT can suddenly become unexpectedly useful. In Scrabble, two-letter words are often used only as a last resort.
