Morphology

stack + up

The meaning 'to accumulate' is directly derivable from combining 'stack' (to pile items) with 'up' (indicating upward increase or completion): piling things up naturally leads to a larger amount over time. This compositional motion/increase pattern is common cross-linguistically and follows a standard English verb+particle meaning, so a B1 learner who knows both constituents would likely infer the MWE's sense.

Etymology

Stack up (meaning to collect or build a larger amount) comes from the picture of small items being added again and again until they stack up into a tall pile, so it now means 'to gather or build up over time'.
