Properly [it means] iron.
"Having plunged Ares inside [your] hollow flanks."¹
It also means war. [The term comes] from the [verb] r(w= [meaning] "I speak,"² (future r(h/sw), [whence] r(h=s, and with the alpha privative [it is] Ares. For in war there is no need of words, but of actions. And Homer [writes]: "for the outcome of war [lies] in hands, [that] of words in counsel."³ The alpha [is] both long and short. Homer [writes]: "Ares, Ares, bane of men."⁴
It is declined *)/arhs *)/arou and *)/arhs *)/arhtos, and *)/arhs *)/areos. For [the nominative] is *)/arhs and mixes its declension.
