Debris
early 18th century: from French débris, from obsolete débriser ‘break down’.
wiktionary
Borrowed from French débris, itself from dé-(“de-”) + bris(“broken, crumbled”), or from Middle French debriser(“to break apart”), from Old French debrisier, itself from de- + brisier(“to break apart, shatter, bust”), from Frankish *bristijan, *bristan, *brestan(“to break violently, shatter, bust”), from Proto-Germanic *brestaną(“to break, burst”), from Proto-Indo-European *bʰrest-(“to separate, burst”). Cognate with Old High German bristan(“to break asunder, burst”), Old English berstan(“to break, shatter, burst”). German bersten More at burst.
etymonline
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").
