Morphology

fill + up

The meaning 'to eat until one is completely full' is directly derived from 'fill' (to make full) combined with the particle 'up', which signals completion or fullness. This compositional completion pattern is common in English and other languages, so a B1 learner who knows both constituents would readily infer the MWE meaning.

Etymology

The verb fill up comes from the simple act of putting material into a space until there is no room left. Think of pouring plaster into a hole or petrol into a tank until it reaches the top, so it means 'make something completely full'.
