Forms
armus m (genitive armī); second declension[1]
Etymology
It is inherited from Proto-Italic *ar(a)mo-, inherited from Proto-Indo-European *h₂erH-mo- (“arm”).[2] De Vaan prefers this full-grade form, since a zero grade would have given ⟨*ramus⟩ in Latin, but he cannot completely exclude it.[2] Cognate with Sanskrit ईर्म (īrmá-, “arm, shoulder”) and Old Prussian irmo (“arm”), and with English arm.[2][3]
Earliest recorded meaning
De Vaan and Köbler find it first in Plautus,[2][4] in a fragment where someone says that like a wolf he is strong in the shoulders but has broken haunches.[3]
Semantic evolution
It is the forequarter or shoulder of an animal, as opposed to umerus, the shoulder of a man, and also its side.[3][5] Horace uses it of a shoulder joint for the table, the forequarters of a pregnant hare.[3] In poetry it is used of a man's shoulder: Virgil has the exclamation "what a brave breast and shoulders!"[3] Döderlein describes it as the top of the upper arm in people and the foreleg in beasts, the shoulder as part of the body.[6] The Mulomedicina Chironis has a third-declension plural armora.[7] Stelten gives "shoulder" for Church Latin.[8]
