Morphology

Ockham's + Razor

This is an eponymous, metaphorical term: 'Ockham's' is a proper name and 'razor' is a literal cutting tool, but the intended sense ('prefer the simplest explanation') is a specialized metaphorical principle. A B1 learner who knows the constituent words would not reliably infer this philosophical meaning without prior exposure or cultural/disciplinary knowledge, so it is not compositionally predictable.

Etymology

Ockham's Razor comes from a monk named William of Ockham long ago, who used the image of a razor to 'shave off' extra ideas from an explanation. So it means choosing the 'simplest explanation' when several ideas can explain the same thing.
