Morphology

ice + up

The meaning 'to become covered with ice' is directly compositional from 'ice' (frozen water) plus the resultative/particle sense of 'up' indicating change into a state or completion. This motion/state-formation pattern is common and transparent cross-linguistically, so a B1 learner who knows the words will readily infer the MWE's meaning.

Etymology

The phrasal verb ice up comes from the simple image of ice forming up on a surface, like windows or pipes when water freezes. That's why ice up now means 'to become covered with a layer of ice', often making something slippery or unusable.
