Forms
foudre f (plural foudres)[4] Old French fuldre, fuildre, fodre; the form foudre dates from the end of the 12th century.[3][5][6]
Etymology
The word for lightning is inherited from Old French fuldre, inherited from Vulgar Latin *fulgura, the neuter plural of Latin fulgur (“flash of lightning”) taken as a feminine singular.[3][1][5][7] The Latin noun comes from fulgeō (“to flash, shine”), of a family that Rey traces to an Indo-European root Proto-Indo-European *bhleg- (“to shine”).[3] In Classical Latin fulmen meant the thunderbolt and the noun from which this word comes meant the flash.[8][9][3] The former disappeared in Late Latin and the latter took over its sense.[8][9][3] The TLFi presents the word as taken from the Latin plural.[8]
Bloch and Wartburg explain the feminine gender by the Latin plural, but derive the Old French form fuildre from a Late Latin fulgerem, like Old Occitan folzer, and Italian folgore from a form *fulgurem.[9] Littré also cites foldre.[6]
Earliest recorded meaning
It is first found in the Chanson de Roland (about 1100), for lightning: Chéent i fuldres et menut et souvent “lightning bolts fall there, thick and often”.[8][6]
Semantic evolution
By comparison the word named the flaming bolt held by Jupiter (1604), in the masculine, and by analogy with its destructive force the firepower of a weapon.[3] Since lightning was taken for a sign of divine anger, foudre came to mean a condemnation or reproach (1594), now in the plural (1728), and les foudres de l'éloquence (1690) the arguments that crush an opponent.[3][8] The masculine foudre de guerre (1559), a warrior nothing can resist, is now ironic.[8][3]
From the suddenness of lightning, coup de foudre meant a disconcerting event (Corneille, 1642).[8][3] Since 1813 it has meant sudden and violent love.[8][3] The word is feminine in ordinary use, but elevated language and poetry may make it masculine.[6]

Forms
foudre m (plural foudres)[4] An isolated 15th-century voudre “cask for Rhine wine” comes from voeder.[3][9]
Etymology
The word for the large cask is borrowed from German Fuder (“cartload, measure for liquids”), recorded in 1669.[3][1][2][12] The German word continues Old High German fuodar, fodar (“cart”), and Middle High German vuoder (“cartload, liquid measure”).[3][4] Picard had voder “a measure” in the 13th century, and the 15th-century voudre was taken from Middle Dutch voeder (“wine measure”), itself from German.[3]
Cognate with the English word fother, Dutch voer and Dutch voeder.[4]
Earliest recorded meaning
Furetière's dictionary (1690) defines it as un grand vaisseau dont on se sert en Allemagne “a large vessel used in Germany”;[9] an earlier record has six voudres de vin du Rhin “six tuns of Rhine wine” in the 15th century.[9][3]
Semantic evolution
Despite its clash with the word for lightning, the cask name survived, but it remained technical or rare, for a cask of 50 to 300 hectolitres.[3][2]
Timeline
- 15th century – Voudre is used for a cask of Rhine wine.[9][3]
- 1669 – Foudre is borrowed from German.[3]
