Forms
reflux m (uncountable)[1] Older spelling reflus (Desportes); reflot was also used.[2][3]
Etymology
It is formed from French re- + flux,[4][5][6][7] and corresponds to the verb refluer.[3] The base is from Latin fluxus (“a flowing”), from fluō (“to flow”).[6] The TLFi dates the first record 1520, earlier than the 1532 of Bloch and Wartburg and the Grand Robert.[4][6][5]
Compare Italian riflusso.[2]
Earliest recorded meaning
Letters patent of August 1520 on the founding of Le Havre speak of flux et reflux de la mer, the rising and falling tide.[4]
Semantic evolution
The word first named the ebb of the sea, the falling tide.[4][3] In the second half of the 16th century Philippe Desportes used it as an image, of a fickle heart and of a crowd moving back (1573),[4][8] and it came to mean any backward movement or withdrawal.[3] Le flux et le reflux came to stand for the ups and downs of human affairs.[2][8]
Medicine uses it for the flow of a liquid in a natural duct against its normal direction (reflux gastro-œsophagien),[9][4] and chemistry for a distillation set-up (appareil à reflux).[4]
