Morphology

eat + away

The sense 'to gradually wear away or erode' is directly derivable from combining 'eat' (to consume/use up) with 'away' (indicating removal or disappearance); the particle adds a sense of progressive removal that is predictable. This verb+particle pattern is a common compositional metaphor in English (and has parallels in other languages), so a B1 learner who knows both constituents would very likely infer the meaning.

Etymology

The phrasal verb eat away also paints a picture of something like doubt, rust, or worry slowly eating at a person or object and taking strength away a little at a time. That's why it now means 'to gradually wear away or erode'.
