Origin of avalanche

  • French Provençal lavanca ravine perhaps ultimately from Latin lābī to slip

    From American Heritage Dictionary of the English Language, 5th Edition

  • From French, from Franco-Provençal (Savoy) avalançhe, blend of aval ‘downhill’ and standard lavençhe, from Vulgar Latin *labanka (cf. Occitan lavanca, Italian valanga), alteration of Late Latin labina ‘landslide’ (cf. Franco-Provençal (Dauphiné) lavino, Romansch lavina), from Latin labi ‘to slip, slide’.
