Ah... I think I may have confused "deductions" with "predictions". Thank you.
So what kind of meaning is this conditional? In grammar books, they talk about factual, predictive, hypothetical and counter-factual.
It's just that the verb forms don't match any of the "formula" taught in class. So I don't know what kind of meaning is implied in this sentence:
If she's not in the office, she has probably left.
Do we know for sure she's not in the office? If we know for sure, why is "if" used?
