Morphology

eat + up

The meaning is directly built from 'eat' (to consume) plus the particle 'up', which commonly marks completeness in English phrasal verbs; therefore a learner who knows both words can infer 'eat up' as consuming or using something entirely. This compositional completive pattern is productive and cross-linguistically recognizable, so the phrase is immediately understandable rather than idiomatic.

Etymology

Eat up comes from the simple picture of finishing every last bite on your plate: eat is to chew and up shows it is finished. So, it means 'to finish eating everything'.
