Pronunciation

  • UK: /ˈfluːənt/[1]
  • US: /ˈfluənt/[1]

Etymology

It is borrowed from Latin fluēns (“flowing”), the present participle of fluō (“to flow”).[2][3][4][5][6] In Latin the participle could also mean "lax, relaxed".[6] The verb is traced to Proto-Indo-European *bhleu- (“to swell, well up, overflow”),[6][4][3] the source also of flūmen (“river”);[6] Barnhart gives the extended form as Proto-Indo-European *bhleugw-.[3] It is related to fluid, flux and affluent.[7][8][9] The rare noun, a stream, is from fluentum (“stream”).[10]

Earliest recorded meaning

Of a speaker, ready with words, able to express oneself easily: 1589, in William Warner's Albion's England.[2][3] Etymonline gives both this sense and "flowing freely", of water, from the 1580s,[6] and Merriam-Webster dates the sense "flowing" to 1585.[10]

Semantic evolution

The literal sense "flowing" is recorded in the OED from 1607, in Topsell's book of beasts, which also has fluent hair, abundant and falling in curves;[2] "fluid, liquid" follows in 1611 and figurative uses of things compared to a stream in 1642.[2] Bacon used it of speech and style flowing easily from tongue or pen (1625).[2] In the 17th century it was used interchangeably with fluid in the sense "changeable, not rigid",[6][2] and Weekley notes that the two words were not always kept apart, quoting "the most fluid preacher in the age of Queen Elizabeth".[7] Two senses have died out: "flowing freely, abounding" (before 1592 to 1682) and "giving freely, generous" (1633 to 1887, later only in dialect).[2][5] In south Cheshire fluent still meant liberal at the end of the 19th century.[11] Johnson (1755) defined it as "liquid", "flowing" and "ready; copious; voluble", and also had a noun for a stream.[12] Berkeley used it in 1734 in the mathematics of fluxions, of a quantity increasing or decreasing continuously,[2] and Blackmore in 1869 of easy, graceful movement.[2] Collins now lists first the sense of ease in speaking or writing a foreign language.[13]
