Morphology

pile + up

The sense 'to arrange into a heap' or 'to accumulate' is directly derivable from combining 'pile' (to heap) with the particle 'up' (indicating increase or accumulation). This verb + particle composition is a common, productive pattern in English and would be predictable to a B1 learner who knows the constituent meanings.

Etymology

Pile up comes from the simple picture of putting things on top of each other to make a high pile and go up as more things are added. When many items keep coming and form a heap, they 'pile up', so the phrase means 'to collect' or 'to increase'.
