5-letter words starting with O

There are 352 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.

A green tile in slot one is the least ambiguous information Wordle gives you, because it fixes both the letter and its position in a single guess. 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.

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.

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.
