Morphology

reductant = reduce (transparent) = reduct + ant

Formed from the combining stem 'reduct-' (related to the verb 'reduce') plus the agentive suffix '-ant'; learners who know 'reduce' and common agentive suffixes can infer 'a substance that reduces'.

Etymology

Reductant comes from the verb reduce, which means 'make smaller' or 'take away', and the ending -ant meaning 'one that does'. In chemistry, to reduce a substance is to add electrons to it, so a reductant is the thing that 'gives electrons' to another substance and so causes the other to become reduced.
