Morphology
stop + up
The meaning 'to fill or block something so that nothing can pass through' is directly derived from 'stop' (to prevent movement or flow) combined with the particle 'up', which here conveys closure or completion; together they form the productive phrasal-verb pattern 'verb + up' meaning to seal or completely halt flow. This compositional pattern is common and predictable, so a B1 learner who knows the constituents would likely infer the intended meaning.
Etymology
Stop up comes from the simple image of putting something into a hole or pipe to stop it up, like stuffing a cloth into a leak so water cannot pass. That's why it means 'to fill or block something so that nothing can pass through'.
