How to use this page
To use this page, start with the search box. Type the letters on your rack, add a question mark for each blank, and press search. The tool keeps this page's constraint and returns only the words you can spell. Below the box, the full list is arranged with common words first, followed by the quick facts, definitions and related lists.
Tips
A blank tile is the most powerful piece on your rack because it stands in for any letter. When you search this list with a blank, the tool underlines the letter the blank replaced so you know which tile to lay down. Spend a blank only when it unlocks a long word or a premium square; using it for a three-letter play is almost always a waste. If you hold two blanks, look for a word from this list that needs both, because a seven-tile play with the bonus outscores nearly everything else.
Questions

Why are some of these words unfamiliar?
599 of the 922 words on this page are tagged rare, meaning they fall outside the usual spell-check vocabulary. They are still real words, and many are legal plays, but you should expect a challenge if someone asks you to define them.
