How Many 5-Letter Words Start With O and End in S?
Locking O at the front and S at the back still leaves 75 words — more than about 87% of the start/end shapes we track. 0 of those sit in the answer pool.
Square two spreads thin: R tops the table at 8 words out of 75 and U follows with 7, so the middle of the word is where your remaining guesses should go.

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 0 words that could truly win the board.

O···S Words by Vowel Count & Second Letter
Vowel structure is the fastest way to narrow the middle three squares. Here is how the 75 O···S words split by how many vowels they contain in total:
| Vowels | Words | Share |
|---|---|---|
| 1 or fewer | 1 | 1% |
| Exactly 2 | 57 | 76% |

And the most common second letters among O···S words — handy when a yellow tile hints at the square right after O:
| Pattern | Words |
|---|---|
| OR···S | 8 |
| OU···S | 7 |
| OA···S | 5 |
| OB···S | 5 |
| OM···S | 5 |
| OD···S | 4 |
