Take an instance with some of the most common English prepositions: in, on, at, below, and above.
- The noun "aircraft" goes with "on", but is the sentence "Parachuters jump off the plane" must be used in this context? Can it go with "out of"?
Take an instance with some of the most common English prepositions: in, on, at, below, and above.
If I get off a plane, it means that the plane is on the ground and I am simply disembarking on foot. If I get out of a plane, it means that I am using an unconventional method of leaving the plane -- it might be still airborne if I am a parachutist; or it might be on fire and I am using the emergency slide; or it might be (from Kate Bunting's comment) that it's a small plane that you have to climb out of, instead of leaving it on foot.
This mirrors the opposite usage: if I get on a plane, I am boarding it in the normal way, on foot. If I get into a plane, I am crawling in through a window, or something similar.
So your notion of "relative" prepositions is valid here.
