Word Origin and History for crevasse

1823, of glaciers; 1814, of riverbanks (in that case from Louisiana French), from French crevasse, from Old French crevace "crevice" (see crevice). Essentially the same word as crevice, but re-adopted in senses for which the meaning that had taken hold in crevice was felt to be too small.

crevasse in Science
  1. A deep fissure in a glacier or other body of ice. Crevasses are usually caused by differential movement of parts of the ice over an uneven topography.

  2. A large, deep fissure in the Earth caused by an earthquake.

  3. A wide crack or breach in the bank of a river. Crevasses usually form during floods. ◇ The sediments that spill out through the crevasse and fan out along the external margin of the river's bank form a crevasse splay deposit.
