effluent: [19] Effluent is that which ‘flows out’. The word comes from the present participle of Latin effluere, a compound verb formed from the prefix ex- ‘out’ and fluere ‘flow’ (source of English fluctuate, fluent, fluid, flux, and a host of derivatives). English originally acquired it as an adjective in the 18th century, but did not begin to use it in its present-day noun senses until the mid 19th century. From the same source come effluvium [17] and efflux [17]. => fluctuate, fluent, fluid, flux
effluent (adj.)
mid-15c., from Latin effluentem "flowing out" (see effluence). As a noun, "that which flows out," from 1859; specific meaning "liquid industrial waste" is from 1930.
