Pronunciation

Forms

alluvial (feminine alluviale, masculine plural alluviaux, feminine plural alluviales)[1]

Etymology

It is formed from French alluvion + -al, from the stem of the noun with the adjective suffix.[2][3][4][5] The noun is from Latin alluviō (“flood, deposit of soil”), from alluō (“to wash against”).[5] Hatzfeld and Darmesteter instead derived the adjective from Latin alluvius.[6]

Earliest recorded meaning

The first known use is in an 1802 French translation of F. Hornemann's Voyage dans l'intérieur de l'Afrique, which asks whether a country is not an alluvial territory, flooded each year when the Niger overflows.[7][3][8]

Semantic evolution

Rey notes that the adjective was used at first mainly in law and then in geology.[8] For a time it had a rival, alluvien (1836 in Rey, 1838 in the Grand Robert), which was given up.[8][3] The Académie's supplement of 1842 defines it as having the character of an alluvion or being produced by one, with plaine alluviale as an example.[2] In the TLFi it is a term of geology and soil science; it is rare of the soil itself and usual of a stretch of land, as in plaine alluviale.[2]

Timeline

  • 1830 – Date given by Bloch and Wartburg.[5]
