Forms
mōriō m (genitive mōriōnis); third declension[1]
Etymology
It is formed from Latin mōrus1 (“foolish”) + -iō, from the adjective borrowed from Ancient Greek μωρός (mōrós, “dull, foolish”).[2][1][3] In antiquity Augustine already called it a word derived from Greek, while Isidore of Seville derived it from mors (“death”), because such a person's mind is not alive.[3]
Earliest recorded meaning
It is first found in Martial,[4] of a fool kept for amusement;[2][5] Pliny the Younger also writes of one in his letters.[5]
Semantic evolution
It names an idiot kept in a household as a laughing stock, a fool.[2][5] Martial also uses it of a deformed person, a monster.[5] Augustine says that people of such stupidity that they hardly differ from cattle are commonly called moriones.[5]
In Medieval Latin, also spelled murio and muro, it meant a fool or simpleton, and also a boor, a rogue or a villain.[6] Gregory of Tours uses it.[4]
