Forms

profond (feminine profonde, masculine plural profonds, feminine plural profondes)[1] Old French parfunt, parfont (about 1100); profond from the late 14th century, with a few earlier isolated records.[2][3][4]

Etymology

It is inherited from Old French parfunt, inherited from Latin profundus (“deep; dense; boundless”) with a change of prefix, remade under the influence of the Latin word, “profundus” is formed from prō- and fundus (“bottom”) (see fond).[2][3][5][6][1][7] Because “par-” was felt as the intensive prefix “very” and “-funt” as a simple adjective, “parfond” gave way to “profond”; it survives in the dialects of the north-east.[2][4]

Old Occitan preon and “pregon” come straight from “profundus” with the first vowel dissimilated to /e/.[2][4] Compare Spanish profundo and Italian profondo.[8]

Earliest recorded meaning

In the Chanson de Roland (about 1100) parfunt describes deep valleys: Li val parfunt et les ewes courant.[2][8] The new form profond is used by Oresme (late 14th century) of water whose bottom is far from the surface.[2][6]

Semantic evolution

It was soon used of ditches (1476), of wounds that go deep (1492), of what lies far below ground (1580) and of a body of troops drawn up in depth (1559, Amyot).[2] Figuratively it described a mind that goes to the bottom of things (about 1480), sciences profondes “great learning” (1534, Rabelais), a scholar (1636), an intense and lasting feeling (1524–1527) and an extreme state such as ennui profond (1668).[2][3]

As a noun le profond “the deepest part” dates from 1529; in thieves' slang of 1790 a profonde was a pocket.[2] In Belgian French an assiette profonde is a soup plate.[3] The adverb profondément and the noun profondeur (1377, earlier parfondor) go with it.[4]
