arma

ar-ma lat.

vgl. agr. ᾰ̔́ρμᾰ hárma, Armee

Etymology 1

From Proto-Indo-European *h₂(e)rmos (“fitting”), from the root *h₂er- (“to join”). armentum is an independent derivation from the same root, as if from Proto-Indo-European *h₂er-mn̥-tom. Cognates include Sanskrit ऋत (ṛtá, “order; right; agreement etc.”) and अरम् (áram, “fitting”), Ancient Greek ἀραρίσκω (ararískō, “to fit together”) and Old Armenian արարի (arari, “I made”).

Semantic development was "that what is fitted together" → "tools" → "weapons". Also related to ars, artus, rītus.
