Where our words, definitions and frequency data come from, how the tools find words, and what the limits are.
Our tools use ENABLE (Enhanced North American Benchmark Lexicon), a public-domain word list created for word game software. We keep every word of up to 15 letters and add six newer words that are now widely accepted in word games (QI, QIS, ZA, ZAS, EW and OK), which gives 168,412 words, and remove a small number of slurs and offensive terms. ENABLE is close to the word lists used in North American word games, but tournament dictionaries add and remove words over time, so a word valid here may not be valid in an official game, and the other way round.
Word pages show definitions from WordNet 3.1, a lexical database of English built at Princeton University. For forms like plurals and past tenses, we show the definitions of the base word and say which form it is. We only build pages for the 5,000 most-used words that have a WordNet entry, so every page has a real definition.
To decide which words are “common” and which come first in results, we use word frequencies from wordfreq, an open dataset by Robyn Speer that combines Wikipedia, news, books, subtitles and web text. A word counts as common when it is used about once per million words or more (a little higher for very short words, so that abbreviations do not slip in). 21,925 words in our list pass this test.
Your letters are counted, and every word in the list is checked to see whether it can be built from those letters. Each blank tile can stand in for one missing letter. Because the full list is checked every time, results are complete: nothing is cut off or sampled. All of this happens in your browser, so your letters are never sent to our server.
Points are the face value of each word: the sum of its letter values, using either classic tile values or Words With Friends values (see letter points). Board bonuses are not included, and letters played with a blank count as zero.
