S is the most strategically important final letter in Scrabble. Adding S to any word already on the board scores for the new word plus potentially hooks into other words. Words naturally ending in S include ACROSS, BONUS, CAMPUS, CLASS, DRESS, FOCUS, GUESS, MINUS, PROCESS, STATUS, STRESS, and SUCCESS.
Never waste an S tile on a word naturally ending in S unless the total score is exceptional. Save S tiles to add to existing board words as hooks — the S is worth far more as a hook extension than as a letter in a terminal -S word.
Our dictionary contains 103,902 words ending with the letter S, drawn from a database of 270,000+ real English words valid in Scrabble, Wordle, and crossword puzzles.
