Every result Letter Smash returns — every unscrambled word, every Scrabble score, every crossword match — comes from a single, carefully maintained word list. Because that dictionary is the foundation of everything we do, we think you deserve to know exactly what is in it, where it comes from, and how we keep it accurate.
A broad English word list drawn from trusted public-domain dictionaries and word corpora.
The dictionary loads into your browser, so searches are instant and your letters never leave your device.
Every entry is a real word from a recognized source — we do not pad the list with machine-generated strings.
We review the list regularly, correcting errors and folding in reader-reported fixes.
The Letter Smash dictionary contains more than 370,000 English words. That includes everyday vocabulary, plurals and verb forms, longer and more obscure words that turn up in competitive play, and the short two- and three-letter words that are the backbone of tile games. It is deliberately broad: a word finder is only as useful as the words it knows, so we err on the side of inclusion for recognized English words.
The list focuses on words that are genuinely valid English. We do not inflate the count with random letter combinations, so the number you see reflects real, usable words rather than padding.
Our word list is compiled from trusted, openly available sources — primarily public-domain dictionaries and well-established English word corpora that have been used and vetted by developers and linguists for years. Building on public-domain foundations lets us offer a comprehensive dictionary for free, without licensing restrictions that would force sign-ups or paywalls.
These sources are combined, de-duplicated, and normalized into a single clean list: consistent casing, no stray punctuation, and no duplicate entries. The result is one unified dictionary that every tool on the site shares.
Compiling from multiple sources means occasional oddities — a typo that slipped through in an old file, or an entry that is really an abbreviation rather than a word. We filter the combined list to remove obvious non-words, entries with invalid characters, and duplicates. When a reader reports a word that should or should not be there, we investigate against reference sources and correct the list accordingly.
Our goal is a list you can trust for study and casual play. If you ever find a word that looks wrong — or a word you expected that is missing — please tell us. Reader feedback is one of the most valuable ways we keep the dictionary accurate.
Every tool draws on the same underlying word list, then applies its own logic on top:
The dictionary tells us which words are valid; the point values tell us how much they score. For game tools we apply the official letter values published for each game — for example, Scrabble and Words With Friends assign different values to the same letters, which is why the highest-scoring play can differ between the two. We apply each game's own values so scores match what you would see on the real board. Premium squares (double and triple letter or word bonuses) depend on where you place a word, so our scores reflect the base value of the tiles; the board multipliers are yours to maximize.
When you first open a tool, the dictionary loads directly into your browser. From then on, every search happens locally on your device — there are no server round-trips. This has three big benefits: results appear in milliseconds, the tools keep working even on a slow or dropped connection, and the letters you type are never collected, stored, or transmitted. Your words stay yours.
Language changes and no word list is ever truly finished. We review the dictionary periodically, correcting reported errors, removing entries that do not belong, and folding in fixes. Because the list is shared across every tool, a single correction improves the whole site at once.
It is worth being clear about one thing: Letter Smash is an independent tool and our dictionary is not the official word list of any single game. Competitive Scrabble, for instance, uses specific tournament lexicons (such as TWL in North America and Collins internationally) that differ from one another and are updated on their own schedules. A word that scores in our finder is valid English, but for sanctioned tournament play you should always confirm against the official lexicon for your region and event.
For everyday games, homework, crosswords, and vocabulary practice, our broad, general-purpose dictionary is exactly what you want: comprehensive, fast, and free.
