Pronunciation

  • Classical: [muːˈniː.ti.oː][1]
  • Ecclesiastical: [muˈnit.t͡si.o][1]

Forms

mūnītiō f (genitive mūnītiōnis); third declension[1]

Etymology

It is formed from Latin mūniō (“to fortify”) + -tiō, a noun of action.[2][1][3] De Vaan derives mūniō, older ⟨moeniō⟩, from moenia (“defensive walls”), from Proto-Italic *moini- (“protective wall”), perhaps from Proto-Indo-European *(H)moi-ni- (“construction”).[4]

Earliest recorded meaning

De Vaan and Köbler date it from Sisenna,[4][3] who has sub hostium mūnītiōnem succēdunt, “they come up under the enemy's fortification”.[2]

Semantic evolution

Mūnītiō is the building of defensive works, “fortifying”, also the walling-in of a besieged place (Cicero: mūnītiō Thessalonīcae), and concretely, often in the plural, “a fortification, defence work”.[2][5][1] It is also the building up of a road with a firm surface (Cicero: ex viārum mūnītiōne, “from the making of roads”), and figuratively a support for a cause.[2][1]

Church Latin glosses it “fort, entrenchment”.[6] Medieval Latin adds “protection”, “a protected place”, “a charter” and “the validation of a deed”.[7] English munition comes from it through French in the 1530s, first as “fortification”.[8]
