About this word list
At 297 words, this list covers common playable words alongside lesser-known entries accepted in competitive Scrabble. Among these entries, 200 contain rare tiles that can dramatically boost your score when played on double- or triple-letter squares. Watch for recurring suffixes like -LY, -ON, -AL, -ION when planning hooks and parallel plays. The highest-scoring word shown is benzdioxdiazine at 44 points. Wordle players can use this list to build a mental model of valid pattern words before guessing — especially when narrowing by known greens and yellows. Words with Friends shares most of these entries; the average score of 31.4 points reflects standard tile values without board multipliers. The average vowel-to-consonant ratio here is 0.39, which affects how easily you can form these words from a random seven-tile rack.

Strategy & study tips
Premium letters drive the top of this list. Prioritise words with Q, X, Z, J, or K when double- and triple-letter squares are open — raw tile value here often exceeds 15 points before multipliers. About 100% of sampled words include a high-value letter (Q, X, Z, J, or K) — useful when planning premium-square plays.

Frequently asked questions
- How is this different from a general length list?
- This page filters by both exact word length and a required letter. For example, 5-letter words with Q excludes 4- and 6-letter entries, giving you a tighter list for Wordle-style constraints or rack-specific study.
- How many words match this pattern?
- Our dictionary contains 297 words matching this pattern. The average length is 15 letters and the average Scrabble score is 31.4 points. The highest-scoring entry shown is benzdioxdiazine (44 pts).
- Are there high-scoring words in this list?
- 200 words in this sample include premium letters (Q, X, Z, J, or K). These are strong candidates for double- and triple-letter square plays in Scrabble.
- Can I find 15-letter words without X?
- Use the Pattern Finder with length set to 15 and "exclude letters" set to X to see words of that length that do not contain the letter.
- Is this page useful for Wordle?
- Yes. Wordle uses 5-letter words, so length-filtered lists and pattern pages help you validate guesses and build a mental dictionary of allowed combinations before you play.

- Yes. Results are drawn from a standard English word list that aligns closely with the official Scrabble dictionary. All displayed words are accepted in competitive Scrabble play.
- Can I use these words in Words with Friends?
- Most Scrabble-valid words are also legal in Words with Friends. The two games use slightly different word lists, but the overlap is large. Use this list as a solid starting point for either game.
- How are the point scores calculated?
- Scores are the raw sum of standard Scrabble letter values (A=1, B=3, C=3, D=2 … Z=10) without board multipliers. Higher-scoring words contain rarer letters like Q, X, or Z.
- Can I combine multiple pattern filters?
- Yes. Use the Pattern Finder to combine starts-with, ends-with, contains, exact length, include letters, and exclude letters in a single search — the same engine that powers these curated lists.
