French débris, from Old French debrisier, to break to pieces : de-, intensive pref.; see de- + brisier, to break (from Vulgar Latin *brīsāre, to press grapes, probably of Celtic origin).(American Heritage® Dictionary of the English Language, Fourth Edition)
Borrowing 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 *brestan (“to break violently, shatter, bust”), from Proto-Germanic *brestanan (“to break, burst”), from Proto-Indo-European *bhrest- (“to separate, burst”). Cogante with Old High German bristan ("to break asunder, burst"), Old English berstan ("to break, shatter, burst"). More at burst. (Wiktionary)
