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 is also used for feelings: think of swell meaning 'to grow' and up meaning 'to rise', like a wave or balloon getting bigger inside you as the emotion increases. So when a feeling swells up, it means 'to grow stronger' or 'to rise' inside someone.
