Quick answers
How many 10-letter words are there starting with O?
There are 1,291 in our dictionary. Pairing a length with a single known letter is usually enough to cut the candidate pool by more than 90%, which is why this combination is more useful than either filter alone.
Is a 10-letter list useful outside Wordle?
Yes. Crossword grids fix the entry length before you know anything else, and Scrabble boards do the same once you spot an open lane. In both cases a length plus one confirmed letter is the normal amount of information you actually have.
Why does O return more or fewer words than other letters?
Openings are where English is least predictable, so a confirmed first letter narrows the field harder than most solvers expect. Letter frequency in English is uneven enough that a common letter can return a hundred times more words than a rare one at the same length.
Can I change the length or the letter?
Yes. The filter above switches length and letter without leaving the page, and the related lists below move the same letter between first, last, and anywhere. That is usually faster than going back to the parent tool.
Are proper nouns or abbreviations included?
No. Only standard dictionary words appear, which matches what Wordle, Scrabble, and crossword grids accept. If a word you expected is missing, it is most often a name, a hyphenation, or an abbreviation.
