- OPERA: down to 96. It is on the answer list.
- OPENS: down to 104.
What These Words Have in Common

FAQs
Can a Wordle answer start with O?
Yes. OTHER, ORDER and OFTEN all sit on the Wordle answer list, so the pattern is worth playing for rather than ruling out.
Do any of these use the same letter twice?
Yes. ORDER and OFFER are two of them. Crossing off a letter after one grey square is the quickest way to miss an answer like these.
Is OCTAD really a word?
Yes. The cardinal number that is the sum of seven and one. It is not on the Wordle answer list, so keep it for Scrabble.
Which one has the best chance of just being the answer?
OTHER. It is the most ordinary word here that the answer list carries, so it is the guess to make when you want to win the round rather than learn from it.
Are all of these accepted as guesses?
Yes. Every word on this list is a legal guess, including the ones that look wrong. OZENA and OYLET are among them. Only a smaller set sits on the answer list, and those are the ones marked in green.
Which of these would most players overlook?
OAKEN, OCTAL and OCTET. All three are on the answer list, and none is a word you would reach for early, so they are worth remembering once the obvious guesses run out.
