Morphology

swell + up

The meaning 'become larger or rounder' is directly derivable from combining 'swell' (to grow larger) with 'up' (indicating increase/completion or movement to a higher degree). This verb+particle inchoative/completive pattern is common in English (and parallel constructions exist in many languages), so a B1 learner who knows the constituents would readily understand the MWE.

Etymology

Swell up comes from the image of swell meaning 'to grow' and up meaning 'to rise' when something fills with fluid or air and becomes round, like an ankle after an injury or dough in the oven. So, swell up means 'to become larger or rounder' because the inside pressure makes it grow.
