5-letter words containing O

There are 4,564 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.

This is exactly what a yellow tile means: the letter belongs, but not where you put it. The only wasted move is guessing it in the same slot again. It is also how a Scrabble rack works: you hold a letter and need to find anywhere it fits. Scan the list for a word that also tests two or three letters you have not tried yet, rather than picking the first plausible answer. A guess that eliminates possibilities is worth more than a guess that might be right.

A letter counted anywhere in the word matches far more often than the same letter pinned to one end, so these lists stay long even for uncommon letters. 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.

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.

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.
