Pronunciation

Forms

fol (feminine fole, folle)[1] In the Roland the word appears as fol, fols and foz, in Chrétien's Yvain as fol, fos and the feminine fole.[2][3]

Etymology

It is inherited from Latin follis (“bag; bellows”),[4][5][6][1] which, used as an adjective, came to mean "idiot, fool" in Late Latin.[6][7] Bloch and Wartburg explain the shift as a joke comparing a foolish person with a ball full of air, and date it to the 6th century;[8] the DHLF compares the French word ballot.[7] Etymonline gives a Medieval Latin adjective follus (“foolish”).[9]

De Vaan defines the Latin noun as "bag, sack; ball, testicles", connects it with Proto-Celtic *bol- and finds no further etymology,[10] while the DHLF reports a proposed onomatopoeic root Proto-Indo-European *bhol- for blowing and swelling.[7] Its Romance cognates include Italian folle and Old Occitan fol.[8]

Earliest recorded meaning

The first record is the Chanson de Roland, of about 1100, where the word is both noun and adjective for an unreasonable person.[11][12][6] The DHLF dates the Roland 1080.[7]

Semantic evolution

From the beginning the dominant sense was a person out of his mind, and the FEW groups "mad", "foolish, imprudent" and "passionate about something".[7][4] By the early 12th century the word could describe a thing, as in fole pöur "mad fear" in the Voyage of Saint Brendan.[6] The AND records a wide range of further senses, from ignorant, frivolous and rash to wicked, heretical, slanderous and lewd, and of animals wild or untrained.[13]

The Latin sense "bellows" survived from the first quarter of the 12th century to 1561, mostly for a smith's bellows, and Old French also had fol de la coille "scrotum" once.[5][4] In chess the word named the piece now called the bishop from Jean de Meun's Roman de la Rose on, replacing aufin;[6] Montaigne used fol for a court jester in 1580.[6] The modern French word is fou, with fol kept before a vowel and in set phrases.[7]

Timeline

  • c. 1100 – fol and fols in the Chanson de Roland.[11][12][6]
  • 1100–1125 – fol in the fragment of a Roman d'Alexandre from Franche-Comté.[14]
  • 1113–1119 – the first Anglo-Norman record cited by the AND.[13]
  • early 12th century – fole pöur in the Voyage of Saint Brendan; the same text has fols "bellows".[6][5]
  • c. 1177 – fol, fos and fole in Chrétien de Troyes's Yvain.[3]
  • 1275–1280 – the chess piece in the Roman de la Rose.[6]
  • 1580 – a court jester, in Montaigne.[6]
  • 1613 – fou for the chess piece.[6]

Anglo-Norman

The AND heads the word fol and first cites it from 1113–1119; its senses include a congenital idiot or born fool, a nickname for an unfaithful woman and, as a feminine noun, a loose woman.[13] The sense "bellows" appears in England under the spelling fou, from 1121–1125.[15] Middle English fol is from the Old French word,[16] and so is the English word fool, recorded from the early 13th century.[9]

Word family

  • folie
  • folement

Descendants

  • Middle French fol (→ French fou, French fol)[1]
  • Norman fo[1]
  • Middle English fol (borrowed; → English fool)[16][9]

Usage notes

Tobler–Lommatzsch heads the word fol (adjective and noun) apart from fol "beech";[17][18] the DEAF treats the adjective as fol¹ and the bellows as fol³,[11][5] and the AND has fol and fou.[13][15] The DEAF's fol², "greyish (?)" of a horse, recorded once in an Anglo-Norman glossary of the late 13th century, has another, uncertain origin.[19]
