High-value letter density matters: roughly 90 results here include at least one premium tile worth 8–10 points on its own.

Average Scrabble value across the list is 25.1 points per word. Daily Wordle solvers benefit from lists like this when a letter pattern repeats across puzzles; knowing valid words in advance reduces wasted guesses.

Strategy & study tips

When the board already shows the first letters, this page validates every 12-letter continuation before you spend a turn. Average Scrabble value here is 25.1 points — use that as a floor for acceptable plays when board space is tight.

Frequently asked questions
- How is this different from “words starting with”?

- How many words match this pattern?
- Our dictionary contains 1,021 words matching this pattern. The average length is 12 letters and the average Scrabble score is 25.1 points. The highest-scoring entry shown is objectivized (36 pts).
- Are there high-scoring words in this list?
- 90 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.
- 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.

- 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.
