In English one can say:
Without you I would not be here.
This is roughly the same thing as:
If you had not helped, I would not be here.
The exact wording depends on context. In the second example the irreal condition (which is not met) is expressed by a conditional clause, whereas in the first one it is expressed by a prepositional phrase. It occurred to me that I do not recall seeing the first kind of construction in Latin.
Are there examples of an irreal condition expressed by a prepositional phrase in classical Latin? The basic example would be:
Sine te hic non essem.
Or more generally:
Sine X fieret Y.
The verb can by anything. I find sine to be the most likely preposition in this use, but it can be any. I am looking for an irreal conjunctive (imperfect or pluperfect) where the condition (which is not met) is expressed not by a conditional clause but by a prepositional clause. I would prefer examples concerning present time (conjunctive perfect), but past (pluperfect) is also possible.
I have no clue how to search for structures like this, so the best I can do is to ask whether someone here has seen this.
