Middle English, abundant, flowing, from Old French, from Latin affluēns, affluent-, present participle of affluere, to abound in : ad-, ad- + fluere, to flow; see bhleu- in Indo-European roots.
(American Heritage® Dictionary of the English Language, Fourth Edition)
Middle French affluent, from Latin affluentem, accusative singular of affluēns, present active participle of affluō ("flow to or towards; overflow with"), from ad ("to, towards") + fluō ("flow") (cognate via latter to fluid, flow). Sense of “wealthy” (plentiful flow of goods) c. 1600, which also lead to nominalization affluence. (Wiktionary)
