Morphology

oxidation = oxidize (transparent) = oxid + ation

The noun is a standard nominalization of the verb 'oxidize' with the productive suffix '-ation', so its meaning is directly derived.

Etymology

Oxidation comes from oxygen, a name made from the Greek parts oxys 'acid' and -gen 'producer' because early scientists thought oxygen made acids. So oxidation originally meant 'combining with oxygen', which you can see when iron meets oxygen and makes rust, and today it also covers cases where a substance 'loses electrons'.
