5 Letter Words Starting With O and Ending in A
Every five-letter word that fits O _ _ _ A — answer-eligible words are flagged in green, and you can tap any word to play it.
How Many 5-Letter Words Start With O and End in A?
O…A is one of the narrower shapes in the dictionary: 11 five-letter words open with O and close with A, and 2 of them can be the daily answer — OMEGA, OPERA among them. With both ends green you are usually three letters from done.
Square two spreads thin: M tops the table at 2 words out of 11 and R follows with 2, so the middle of the word is where your remaining guesses should go.
100% of these words carry two or more vowels, so the middle is vowel-rich — test consonants with your next probe.
Green-dotted words are answer-eligible — the everyday vocabulary the daily puzzle actually draws from — while hollow-dotted words are valid guesses you can play but that will never be the solution. Flip on Answers only to focus on the 2 words that could truly win the board.
Best Wordle Guesses That Fit O _ _ _ A
Once O and A are green, the strongest follow-up is a word that both fits the pattern and rules out as many remaining answers as possible. These three score highest, measured across all 2296 possible answers:
- 01 OPERA — eliminates about 95.3% of remaining answers on average.
- 02 OMEGA — eliminates about 92.6% of remaining answers on average.
The Full List, Grouped by Second Letter
The chips above split the list by that second square. OM holds 2, OR holds 2, OS holds 2, OU holds 2, with 1 word spread thinner still — pick the group your yellow tile allows and the rest falls away.
O···A Words That Have Been Wordle Answers
The puzzle has been sparing with O…A. Its entire history across 1916 rounds: OMEGA (#1501, 2025-07-29), OPERA (#568, 2023-01-08). Every answer-eligible word here has already had its turn.
| Puzzle | Date | Answer |
|---|---|---|
| #1501 | 2025-07-29 | OMEGA |
| #568 | 2023-01-08 | OPERA |
The other 9 words are valid guesses the game accepts but will never choose as a solution. They are still useful as probes — words you play to expose new letters — but when you are guessing to win, a green-dotted answer word is the smarter pick.
O···A Words by Vowel Count & Second Letter
Vowel structure is the fastest way to narrow the middle three squares. Here is how the 11 O···A words split by how many vowels they contain in total:
| Vowels | Words | Share |
|---|---|---|
| 1 or fewer | 0 | 0% |
| Exactly 2 | 0 | 0% |
| 3 or more | 11 | 100% |
And the most common second letters among O···A words — handy when a yellow tile hints at the square right after O:
| Pattern | Words |
|---|---|
| OM···A | 2 |
| OR···A | 2 |
| OS···A | 2 |
| OU···A | 2 |
| OC···A | 1 |
| OI···A | 1 |
How to Use These Words to Win Wordle
- Pin the second letter first. The square after O splits the list fastest — OM alone accounts for 2 of the 11 candidates, so fixing that tile drops most of the rest.
- Favor distinct letters early. 7 of the 11 words here use five different letters and 4 repeat one.
