Morphology
Murphy's + law
The phrase is an eponymous, cultural idiom: knowing 'law' (a general rule) does not allow a learner to infer the specific content attached to the proper name 'Murphy's'. The meaning 'if something can go wrong, it will' is idiomatic and requires prior exposure, so a B1 learner who only knows the constituents would not reliably derive it.
Etymology
Murphy's Law comes from one popular story about an engineer named Murphy who worked on safety tests; when parts were put in the wrong way he warned that 'if anything can be done wrong, it will be done wrong'. People began calling that bad-luck idea Murphy's Law, and that's why the phrase means 'if something can go wrong, it will go wrong'.
