About this word list
With 12,100 valid entries, this is one of the larger curated lists on unscrambletools.com, sorted by length and Scrabble score for quick scanning. Scrabble players will notice 67 words carrying Q, X, Z, J, or K — letters that separate casual players from competitive ones. Common endings in this list include -LY, -ED, -NG, -ING — patterns that let you extend words already on the board. Notice how many words begin with OV, OR, OP, OVE — memorising these clusters speeds up in-game word retrieval. Top scorer: oxybenzaldehyde (44 pts). Average Scrabble value across the list is 28 points per word. While Wordle uses a smaller answer list, studying broader dictionary patterns here helps you eliminate impossible guesses faster. Words with Friends shares most of these entries; the average score of 28 points reflects standard tile values without board multipliers. With a vowel ratio of 0.4, this list skews consonant-heavy — keep extra vowels on your rack when targeting these words.

Frequently asked questions
