Forms

mur m (plural murs)[1]

Etymology

It is inherited from Latin mūrus (“wall, especially of a city”), in Old Latin “moerus”.[2][3][4][5][1][6] The Latin word was distinct from moenia (“ramparts”) and, from pariēs (“wall of a house”) (see paroi).[3] It is usually connected with “pōmērium”, the sacred strip along the walls of Rome, though the form raises difficulties; it replaced the Indo-European word seen in Ancient Greek τεῖχος (teîkhos, “wall”).[3] Wiktionary traces it to a root “*mey-” “to strengthen”.[1]

Cognate with Italian muro, Occitan mur, Spanish muro and Portuguese muro.[4][6]

Earliest recorded meaning

It is first found at the end of the 10th century in the Passion of Clermont, in the plural, for the walls of Jerusalem: en tos belz murs, en tas maisons pedra ssubr altre non laiseront (“in your fine walls, in your houses, they will not leave stone upon stone”).[2][7]

Semantic evolution

The word first named the fortified wall around a town, and by metonymy the town itself, as in defors li mur “outside the walls” (about 1200), later rivalled by Latin extra muros and intra muros.[2][3] From the Chanson de Roland it was also used of the walls of a house (about 1100) and a castle (early 12th century), and figuratively of protection (Chrétien de Troyes, 1176–1181).[2][3] Modern uses include le mur du son “the sound barrier”, faire le mur “to slip out without leave” and mettre au pied du mur “to leave no way out”.[7] Derivatives include muraille (about 1200), murer (12th century) and emmurer.[4]
