Morphology

Occam's + Razor

This is a named philosophical principle (from William of Occam) whose meaning — that the simplest explanation is usually best — cannot be deduced by a B1 learner from the parts 'Occam's' (a proper name) and 'razor' (a shaving tool) without prior cultural or disciplinary knowledge. Although 'razor' can metaphorically suggest 'cutting away' unnecessary assumptions, that metaphorical mapping and the historical reference are not predictably transparent to learners, making it idiomatic.

Etymology

Occam's Razor is named after the thinker William of Ockham and uses the image of a razor that 'cuts away' extra ideas. So the phrase reminds us to choose the 'simplest' explanation instead of adding many extra parts.
