cadaver (n.) Look up cadaver at
c. 1500, from Latin cadaver "dead body (of men or animals)," probably from a perfective participle of cadere "to fall, sink, settle down, decline, perish," from PIE root *kad- "to lay out, fall or make fall" (see case (n.1)). Compare Greek ptoma "dead body," literally "a fall" (see ptomaine); poetic English the fallen "those who died in battle."
