Morphology

oxidation-reduction = oxidation + reduction (transparent) = oxidation + reduction

The term is a direct compound of the two nouns 'oxidation' and 'reduction' and denotes the paired chemical processes, so its meaning follows directly from its parts for learners who know those terms.

Etymology

Oxidation-reduction joins two older ideas: oxidation comes from oxygen, a name early scientists used because they thought it 'made acids', so oxidation once meant 'adding oxygen', and reduction comes from a root meaning 'to bring back' or 'make smaller', so it meant the opposite. So, an oxidation-reduction reaction is a pair of linked changes where one part is oxidized and the other is reduced — they happen together.
