Morphology

in + case

The meaning 'as a precaution; if something happens' is directly derivable from combining 'in' (within/inside) with 'case' (a particular situation) — i.e. 'in the case (that) ...' → 'if/in the event that ...'. This compositional pattern has clear equivalents in many languages (e.g. Spanish 'en caso de', French 'au cas où') and follows a regular semantic logic, so a B1 learner who knows the constituents will very likely understand it.

Etymology

In case comes from the idea of a case as a certain situation. Think of taking an umbrella 'in case' it rains — you take it to be ready for that situation. That's why in case means 'if something happens' or 'as a precaution'.
