Morphology

principle + of + parsimony

The phrase is compositionally built: 'principle' = a guiding rule and 'parsimony' = frugality/simplicity, so together they denote a rule favoring the simplest explanation. This meaning is directly derivable from the constituent meanings (and mirrors cross-linguistic formulations such as Occam's razor), so a learner who knows both words would understand it.

Etymology

Principle of parsimony comes from the image of a razor that shaves away extra ideas and leaves only what is needed. So, like that razor cutting away the unneeded parts, the phrase tells us to choose the 'simplest' explanation with the 'fewest assumptions'.
