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.

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