Morphology

open + up

The meaning 'to make something open or become open' is directly and predictably derived from 'open' (to remove closure) combined with the particle 'up', which here adds a completive/intensive sense. This verb+particle composition is a regular, cross-linguistically common pattern, so a B1 learner who knows the constituent words would reliably infer the MWE's meaning.

Etymology

Open up comes from the simple action of making something closed become open, like turning a key or pulling a cover up. That's why it means 'to make something open' or to remove a barrier.
