Morphology

reducing + agent

The phrase is compositionally predictable as 'an agent that reduces'—the modifier 'reducing' describes the role of the agent—so a learner who knows both words can form a rough plausible meaning. However, the precise chemical sense (electron transfer / being oxidized) is technical and not inferable from general vocabulary knowledge alone, so a B1 learner would grasp only a vague idea rather than the full, domain-specific meaning.

Etymology

Reducing agent comes from the verb reduce, meaning 'to make less', and agent, meaning 'something that does an action'. In chemistry a reducing agent gives electrons or removes oxygen so another substance becomes 'less' in its chemical state, so today the phrase means 'a substance that causes reduction in another substance'.
