Forms
armātus (feminine armāta, neuter armātum, superlative armātissimus); first/second-declension participle[1]
Etymology
It is the past participle of armō (“to arm”), used as an adjective.[1][2] The verb is from arma (“arms, weapons”),[3] which de Vaan derives from Proto-Italic *armo-, Proto-Indo-European *h₂(e)r-mo- (“fitting”), from the root “to join”: the sense passed from “things fitted together, tools” to “weapons”.[4]
Earliest recorded meaning
Köbler dates it from Ennius,[3] who has segetis armātae, “a crop of armed men”.[1] Plautus has hōc in equō īnsunt mīlitēs armātī atque animātī probē, “in this horse are soldiers, well armed and in good heart”.[1]
Semantic evolution
Armātus is “armed, furnished with weapons”, and “clad in armour” (Cato: the north-west wind can knock over an armed man or a loaded wagon).[1][2][5] It is used of things that involve arms: Cicero has vim armātam, “armed force”, and armāta dissēnsiō cīvium, “armed conflict among citizens”.[1] As a noun armātus, usually plural, is an armed man, a soldier.[1]
Church Latin glosses it “armed”.[6]

Usage notes
A separate fourth-declension noun armātus, armātūs, formed from armō with the suffix ⟨-tus⟩, means a kind of equipment or armour; it is found almost only in the ablative, in Livy and Fronto (haud disparī armātū, “with similar equipment”), and gravis armātus is the heavy-armed troops.[1][2][5][3]
