Morphology

muster + up

The meaning 'to gather or summon (energy, courage, etc.)' is directly derivable from combining 'muster' (to collect or summon) with the particle 'up' (indicating increase or intensification). This follows a common English verb + up pattern that signals gathering/raising, so a B1 learner who knows both constituents should be able to infer the MWE meaning.

Etymology

The phrasal verb muster up comes from leaders calling soldiers to a muster, a meeting where people gathered before battle. So when you 'muster up' 'courage' or 'energy', you imagine bringing it together like troops, and that is why it means 'to collect or bring together strength with effort'.
