Morphology

root + out

The sense 'to find and completely remove' follows directly from combining 'root' (with the physical/metaphorical sense of pulling out by the roots or uprooting) and the particle 'out' (indicating removal). This verb+particle composition and the root-uproot metaphor are cross-linguistically common, so a B1 learner who knows both constituents can reasonably infer the MWE meaning.

Etymology

Root out paints the same picture but for problems: imagine digging up a bad plant by its root until it comes out of the soil. So the phrase is used for 'to find and completely remove something unwanted or hidden'.
