rift n.
early 14c., "a split, a breaking, an act of tearing or rending," from a Scandinavian source (compare Danish and Norwegian rift "a cleft," Old Icelandic ript (pronounced "rift") "breach;" related to Old Norse ripa, rifa "to tear apart, break a contract" (see riven). Probably influenced in Middle English by rive (v.).
