Oppositecertainly, undoubtedly, inevitably
Note
Here the adverb hedges a whole statement rather than an action. It sits between two poles: certainly not on one side, certainly or undoubtedly on the other. Perhaps, maybe and conceivably come closest in meaning.
- 2Used to indicate that an action lies within what can be done, that performing it is not impossible.
There was no way she could possibly reach the summit before dark.
We can't possibly seat three hundred guests in such a small hall.
UsageUsually with can or could, most often negative: can't possibly finish, couldn't possibly be there.
Note
You can't possibly win and I couldn't possibly be there on time rule an action out as beyond reach; I couldn't possibly cheat on my wife uses the same frame for what one refuses to do. In the positive (they could possibly win) it allows that the outcome is not out of reach, close to the "perhaps" meaning but about ability rather than truth.
