Forms
réactionnaire (plural réactionnaires)[1]
Etymology
It is formed from French réaction + -aire, from the noun in its political sense “movement opposed to the progress that followed the Revolution” (1792).[2][3][1] The word arose during the French Revolution, when the noun strongly influenced the family of réagir.[4] réaction itself is a learned borrowing from Medieval Latin reactio.[1]
A rival word, réacteur, was formed by a change of suffix in the same year, 1794, and was used for the partisan of reaction during the 19th century before it gave way to the derivative in -aire.[4]
Earliest recorded meaning
Brunot's history of the French language records it in 1794 for a partisan of the policy of reaction; in 1796 a speech by Isnard reprinted in the Moniteur speaks of crimes réactionnaires.[2] The Grand Robert and the Petit Robert date it to 1796.[5][6]
Semantic evolution
From the Revolution's “partisans of reaction” the adjective widened, keeping its pejorative tone, to any conservative, backward-looking person or attitude: Chateaubriand wrote in 1831 of the mouvement réactionnaire du paganisme under Julian, in the sense “tending to go back”.[2][4] The noun un réactionnaire is found in Flaubert's letters in 1850.[2][4] Littré still marked the word as a neologism, for what works with the reaction against the Revolution.[7]
The familiar clipping réac became very common in 1848, according to Larchey, notably through the comic figure of Monsieur Réac.[2][4][6] Today the word is used polemically in politics, and by extension of whatever opposes social progress or changes in customs.[3][6]
English reactionary (1831) was modelled on the French word.[8]
