Morphology

work + principle

The phrase 'working principle' is a straightforward composition of 'working' (functioning) + 'principle' (foundational rule), so a B1 learner who knows the constituents can infer it means the rule or mechanism that makes something operate. This compositional pattern is common cross-linguistically and follows transparent noun-modifier logic, making the meaning immediately accessible.

Etymology

Working principle comes from the idea of a single rule or part that makes a machine run. Think of working as 'doing the job' and principle as the 'rule' that makes it happen. So working principle means the basic rule or idea that explains 'how something works'.
