Pronunciation

  • Classical: [eːˈmuː.ni.oː][1]
  • Ecclesiastical: [eˈmuː.ni.o][1]

Forms

ēmūniō (present infinitive ēmūnīre, perfect active ēmūnīvī or ēmūniī, supine ēmūnītum); fourth conjugation[1]

Etymology

It is from Latin ex- + mūniō (“to fortify”).[2][1][3] De Vaan treats mūniō under moenia (“walls”), from Proto-Italic *moini- (“protective wall”), and tentatively reconstructs *(H)moi-ni- (“construction”).[4] He compares Latvian mìet (“to drive piles”).[4]

Earliest recorded meaning

Lewis and Short find it no earlier than the Augustan age.[5] In Virgil's Aeneid doorposts are made secure with a barrier: fultōsque ēmūniit obice postēs.[6][3]

Semantic evolution

Livy uses it of a wall built higher than elsewhere at a vulnerable point, and of a place enclosed with squared stone and fortified like a citadel.[7] Columella uses it of protecting vines from cattle with cages and of securing the floors and walls of granaries.[5] Seneca the Elder has a mind armed against fear.[6] Statius uses it of piling couches high with coverings,[2][6] and Tacitus of building roads through woods and marshes, silvīs ac palūdibus ēmūniendīs.[2]
