(comparative more affluent, superlative most affluent)
- Abundant; copious; plenteous.
- (by extension) Abounding in goods or riches; materially wealthy.
- (dated) Tributary.
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.
Only relation to antonym indigent is common Latinate suffix + -ent.
