Every five-letter word that fits R _ _ _ O — answer-eligible words are flagged in green, and you can tap any word to play it.
How Many 5-Letter Words Start With R and End in O?
21 words start with R and end with O, 5 of them answer-eligible. RATIO is the most efficient probe from here, clearing about 96%.
Once both ends are green, the second letter is where the puzzle actually lives — and here it is E far more often than anything else, 43% of the time, as in RETRO.
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 5 words that could truly win the board.

R···O Words by Vowel Count & Second Letter
Vowel structure is the fastest way to narrow the middle three squares. Here is how the 21 R···O words split by how many vowels they contain in total:
| Vowels | Words | Share |
|---|---|---|
| 1 or fewer | 0 | 0% |
| Exactly 2 | 12 | 57% |
| 3 or more | 9 | 43% |
And the most common second letters among R···O words — handy when a yellow tile hints at the square right after R:
| Pattern | Words |
|---|---|
| RE···O | 9 |
| RA···O | 5 |
| RO···O | 4 |
| RU···O | 2 |
| RH···O | 1 |
How to Use These Words to Win Wordle

- Favor distinct letters early. 9 of the 21 words here use five different letters and 12 repeat one.
