Morphology
The meaning 'to yield or submit' is directly derived from combining 'cave' (to give up resistance) with the directional/into-state sense of 'in' — together signalling moving into a state of collapse or submission. This compositional pattern parallels verbs like 'give in' and is likely understandable to a B1 learner who knows the constituent meanings.
Etymology
Cave in comes from the image of a cave or a weak roof suddenly falling down into the space below. That's why it means 'to collapse' or fall down.
