Morphology

clog + up

The verb 'clog' means to cause a blockage and the particle 'up' contributes a sense of completion/intensification, so their combination yields 'to block completely' which a B1 learner can infer from the parts. This is a regular phrasal-verb composition common in English (and paralleled by similar completion markers in other languages), making the expression transparently derivable from its constituents.

Etymology

Clog up comes from the simple image of things getting stuck and filling a narrow pipe or drain. Imagine hair or leaves building up so water cannot pass — the clog fills it and the up shows it is full, so the phrase means 'to block' or 'stop movement'.
