Morphology

top + up

The sense 'to refill or add more credit' is directly derivable from combining 'top' (to add a finishing amount) with 'up' (to increase or bring to a higher level); the particle construction yields a straightforward increase-to-full interpretation. This compositional pattern is common cross-linguistically and in English uses (e.g., topping up fuel or phone credit), so a B1 learner who knows the constituents will readily infer the meaning.

Etymology

The phrasal verb top up comes from the simple image of putting more into a cup or tank so it reaches the top, because you are filling it up. That's why it now means 'to refill' or 'to add more money or credit'.
