debris (n.)

"accumulation of loose matter or rubbish from some destructive operation or process," 1708, from French débris "remains, waste, rubbish" (16c.), from obsolete debriser "break down, crush," from Old French de- (see de-) + briser "to break," from Late Latin brisare, which is possibly of Gaulish origin (compare Old Irish brissim "I break").
