How to use this page
Begin with the search box if you are mid-game: your letters, plus question marks for blanks, produce the playable words instantly. Begin with the list if you are studying: the common words are at the top, the definitions section explains the most useful ones, and the quick facts show the top scorers.
Tips
Hooks are single letters added to the front or back of an existing word to make a new one, and they are the cheapest way to score in a crowded game. Look through the words on this page for ones that become a different valid word with one more letter, or that can be formed by extending a shorter word already on the board. Suffixes such as S, ED, ER and ING, and prefixes such as RE and UN, do most of the work. A hook lets you play a second word in parallel and collect both scores.
