What is the origin of manticore?

While the legends involving manticores were likely tall tales about lions and tigers and similar beasts, manticore is not a compound of English man and tiger, which is a common misconception. Instead, manticore “a legendary monster with a man’s head, a lion’s body, and the tail of a dragon or scorpion” derives via Middle English from Latin mantichōrās, which was a either a variant or a misreading of Ancient Greek martichṓras. This word, in turn, was borrowed from the Old Persian element martiya- “man” and an additional Iranian source akin to Modern Persian -khōr “eat, devour.” The martiya- element descends from a Proto-Indo-European root, mer- “to harm, die”—compare immortal (via Latin) and ambrosia (via Ancient Greek), both literally meaning “not of death”—while the -khōr element is cognate to English swallow and swill. Manticore was first recorded in English in the early 1300s.
