About this word list
At 404 words, this list covers common playable words alongside lesser-known entries accepted in competitive Scrabble. High-value letter density matters: roughly 36 results here include at least one premium tile worth 8–10 points on its own. Watch for recurring suffixes like -LY, -IC, -US, -LLY when planning hooks and parallel plays. The highest-scoring word shown is metempsychosize at 38 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 27.4 points reflects standard tile values without board multipliers. With a vowel ratio of 0.39, this list skews consonant-heavy — keep extra vowels on your rack when targeting these words.

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 18% of sampled words include a high-value letter (Q, X, Z, J, or K) — useful when planning premium-square plays.
Prefix-locked length lists train slot-filling for crosswords and Wordle. Start with the highest-scoring opener, then drill hooks that add one letter before the prefix. Review related searches at the bottom of this page to hop between adjacent patterns without competing URLs in search results. Internal links point to Pattern Finder, Crossword Solver, Anagram Solver, and Wordle Solver — each tool adds interactivity this static list intentionally omits.

Frequently asked questions

- 36 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.
