Etymology

It is from Proto-Italic *moini- (“protective wall”), perhaps from Proto-Indo-European *(H)moy-ni- (“construction”), from a root *mey- “to fix, build”.[2][1] Cognate with Sanskrit मिनोति (minóti, “fixes, builds”), and related within Latin to mūniō “to fortify” and mūrus “wall”.[2][3][1] De Vaan explains the kept /oe/, where /ū/ would be expected, as a way of keeping it apart from mūnia “duties”, and does not rule out a link with mūnus.[2]

Earliest recorded meaning

De Vaan dates it from Naevius, who has a singular moene.[2] Ennius speaks of attacking the walls of the citadel.[3] Köbler dates Naevius c. 235–200 BC.[4]

Semantic evolution

It was the defensive walls of a town, and then the area enclosed by them, a fortified town or city, as when Plautus asks a small space “in your great and lovely city”.[3] In poetry it was also a natural barrier, such as the fiery walls of the world in Lucretius.[3] Isidore says the walls are so called because they fortify (mūniant) the city.[5]

Medieval writers used it of town and borough walls, and figuratively.[6] Its relatives mūniō and mūnītiō gave English munition in the 1530s and, by a French misdivision, English ammunition in the 1620s.[7]

Timeline

Usage notes

Döderlein distinguishes mūrus, any wall by its form, pariēs, the wall of a building or a partition, and moenia, the walls of a city as a defence.[8] Moenia is also an old spelling of mūnia “duties”.[9]
