Pronunciation

  • /ˈæf.lu.ənt/, /ˈæfluːənt/[1]

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]
