Morphology

effluent = ef + flu + ent

The elements correspond to 'out' + 'flow' + adjectival/noun -ent (i.e. 'flowing out'), but the specific technical sense 'liquid waste discharged' is specialized and not fully predictable for an average B1 learner.

Etymology

The word effluent comes from the Latin verb effluere, which means 'to flow out', and is related to common words like flow and fluid. So, effluent means liquid waste that 'flows out' from a factory or sewer into a river or the sea.
