etymonline
manticore (n.)
fabulous monster mentioned by Ctesias with the body of a lion, head of a man, porcupine quills, and tail or sting of a scorpion, c. 1300, from Latin manticora, from Greek mantikhoras, corruption of martikhoras, perhaps from Iranian compound *mar-tiya-khvara "man-eater."
The first element is represented by Old Persian maritya- "man," from PIE *mar-t-yo-, from *mer- "to die," thus "mortal, human;" from PIE root *mer- "to rub away, harm" (also "to die" and forming words referring to death and to beings subject to death). The second element is represented by Old Persian kvar- "to eat," from PIE root *swel- (1) "to eat, drink" (see swallow (v.)).
