affluent

Etymology

It is borrowed from Latin affluēns (“flowing, abounding, rich, abundant”),^[2][3][4] perhaps through Old French afluent,^[3][5][6][7] the present participle of affluō (“to flow toward, abound”),^[2][3][5] from ad- (“to, toward”) and fluō (“to flow”).^[3][5][8][9] The American Heritage Dictionary refers the Latin verb to Proto-Indo-European *bhleu-.^[5] The word has cognates in affluent, recorded before 1471, afluent, afluente, afluente and affluente.^[2] From the same Latin verb come fluent, fluid, flux and effluent.^[10][11][9]

Earliest recorded meaning

Abundant, copious: about 1425, in the Book of the Foundation of St Bartholomew's;^[2] Etymonline describes the early use as "abounding in", of God's grace.^[3] Barnhart dates the sense "flowing in abundance" to 1413.^[8]

Semantic evolution

In the 15th century the word was used both for abundance and, of liquids, for "flowing toward" a place,^[2][3][10] and Johnson (1755) still gave "flowing to any part" as the first sense.^[12] The sense "wealthy, prosperous" has its first OED record in 1652,^[2] which agrees with the Oxford Dictionary of Word Origins' mid 17th century,^[10] while Etymonline dates it to 1753^[3] and Ayto to the mid 18th century, calling it a fairly recent development.^[11] The figurative sense "rich in a quality", especially fluent with words, follows in 1659.^[2] As a noun the word meant the wealthy as a class from 1735,^[2] and a stream flowing into a larger one, a tributary, from 1829,^[2][7] a sense the OED compares with French affluent, tributary (1835).^[2] In American English the stress varies, and second-syllable stress is less common among educated speakers.^[2]
