Morphology

antioxidant = oxidant (semi-transparent) = anti + oxid + ant

The formation with anti- is clear, but the base word 'oxidant' is a technical scientific term rather than a high-frequency everyday word.

Etymology

The word antioxidant begins with anti- meaning 'against' and includes oxygen, the gas that can make metal rust and can harm cells. So, an antioxidant is a substance that works against this kind of damage and helps protect food and the body.
