[edit]Etymology
[edit]From Proto-Italic *arkuos (“bow”), from Proto-Indo-European *h₂erkʷos (“bow, arrow”). Cognate to Old English earh, whence English arrow, as well as Proto-Slavic *orkyta (“willow”) and Ancient Greek ἄρκευθος (árkeuthos, “juniper”), owing to juniper and willow twigs being used to make bows due to their flexibility.[1]
