語源
英語の原文（Wiktionary）
From Middle English quiver, from Anglo-Norman quivre, from Old Dutch cocare (source of Dutch koker, and cognate to Old English cocer (“quiver, case”)), from Proto-West Germanic *kokar (“container”), said to be from Hunnic, possibly from Proto-Mongolic *kökexür (“leather vessel for liquids”); see there for more. Replaced early modern cocker, the inherited reflex of that West Germanic word. The mathematical sense originated as German Köcher in a 1972 paper by Pierre Gabriel; it was likely chosen because a quiver contains arrows, while a digraph contains directed edges (also called "arrows").
