Forms

tonnerre m (plural tonnerres)[1] Old French tuneire (about 1100), toneire (12th century) and tonoire (13th to early 17th century); tonnerre is found from 1553.[2][3][4]

Etymology

It is inherited from Old French tuneire, inherited from Latin tonitrus (“thunder, a resounding noise”).[4][2][1] The regular French outcome tonnoire is attested until 1572, in Amyot, and tonnaire appears in dictionaries from 1573 to Nicot (1606).[4]

The Latin noun is derived from tonō (“to thunder”) (the source of tonner); as Latin had no suffix ⟨-tru⟩, Rey explains it as a blend of a masculine stem in ⟨-tu-⟩ and a neuter stem in ⟨-tro-⟩.[2] The noun spread less widely in the Romance languages than the verb, and most of them made a noun from the verb instead: Italian tuono, Spanish trueno and Old Occitan tron, which competed with toneire.[5][2] Rey compares the Latin group with Old English þunor (“thunder”) and the English word thunder.[2]

Earliest recorded meaning

It is first found about 1100 in the Chanson de Roland, as tuneire, for the noise that comes with lightning: Orez i ad de tuneire e de vent “there are storms of thunder and wind”.[4][6]

Semantic evolution

From the 12th century (about 1160) the word was also used of any deafening noise.[2] By metonymy it sometimes named lightning itself (1440–1475), and the theatre used it for the device that imitated thunder (1743).[2][7] Voix de tonnerre “thundering voice” is found in 1553, and coup de tonnerre for a sudden, unforeseen event in 1623.[4][2]

As an interjection expressing violence or threat it dates from 1790, in oaths such as tonnerre de Dieu and mille tonnerres, which seem to come from sailors' speech.[2][4] From de tous les tonnerres de Dieu (1790) came de tonnerre (1873) and the familiar du tonnerre (1877) “terrific”, a superlative of admiration.[2][4]

Usage notes
