C···O Words by Vowel Count & Second Letter
Vowel structure is the fastest way to narrow the middle three squares. Here is how the 41 C···O words split by how many vowels they contain in total:
| Vowels | Words | Share |
|---|---|---|
| 1 or fewer | 1 | 2% |
| Exactly 2 | 36 | 88% |
| 3 or more | 4 | 10% |
And the most common second letters among C···O words — handy when a yellow tile hints at the square right after C:
| Pattern | Words |
|---|---|
| CH···O | 11 |
| CO···O | 10 |
| CA···O | 8 |
| CU···O | 4 |
| CE···O | 2 |
| CR···O | 2 |
How to Use These Words to Win Wordle
- Pin the second letter first. The square after C splits the list fastest — CH alone accounts for 11 of the 41 candidates, so fixing that tile drops most of the rest.
- Favor distinct letters early. 18 of the 41 words here use five different letters and 23 repeat one.
