Morphology

on + average

The meaning 'typically/usually' is directly derivable from combining 'on' (indicating reference/basis) with 'average' (the mean/typical value); thus the phrase means 'with respect to the average'. This is a common, regular prepositional+noun construction found across many languages, so a B1 learner who knows the constituents will readily understand it.

Etymology

On average comes from the simple idea of the average, the number you get when you add several amounts and divide by how many there are. So when we say on average we mean 'typically' or 'usually' when we look at all cases together.
