Morphology
The meaning 'to stay awake until someone arrives' is directly derivable from combining 'wait' (to stay or postpone action) with 'up' (not asleep/out of bed), so a learner who knows both words can infer staying awake while waiting. This verb+particle composition and the use of 'up' to indicate an awake/state meaning is common and therefore readily comprehensible to a B1 learner.
Etymology
The phrasal verb wait up comes from the simple image of someone staying awake for another person, with wait meaning 'to stay' and up meaning 'awake'. That's why it means 'to stay awake until someone arrives', often to meet or welcome them.
