Why these letters?
Every record holder is built from the most common letters: E, S, A, R, T, L, N and I. These letters combine freely, appear in many endings (-ER, -ES, -ST) and are all worth 1 point, which is why players call them good “rack” letters. Our article on the best six-letter stems shows how the same letters help you play all seven tiles at once.
How common are anagrams?
In our dictionary, 28,547 words (17%) share their exact letters with at least one other word. The share falls quickly with length: short words have lots of anagrams, and long words rarely do. You can find the anagrams of any word with our anagram solver, which also shows two-word anagrams.
