How is this different from “words starting with”?

The general starting-with hub includes every length. This page locks word size (e.g. only 5-letter words starting with S), which matches Wordle and crossword slots more closely.

How many words match this pattern?

Our dictionary contains 403 words matching this pattern. The average length is 15 letters and the average Scrabble score is 28 points. The highest-scoring entry shown is oxybenzaldehyde (44 pts).

Are there high-scoring words in this list?

67 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.

Are these valid Scrabble words?

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.

How many words are in the dictionary?

The dictionary contains over 350 000 English words, covering everything from common 2-letter words to rare 15-letter entries, with proper nouns and abbreviations excluded.

Is this tool free to use?

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 34% 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. Anchor words: highest scorer OXYBENZALDEHYDE, longest OXYBENZALDEHYDE. Build mnemonics around those two before expanding into the full 403 matches. Average Scrabble value here is 28 points — use that as a floor for acceptable plays when board space is tight.
