Where it comes from
Unadapted borrowing from French quillon (literally “little ninepin”), from quille (“club; ninepin, skittle”) (from the similar appearance) + -on (diminutive suffix). Quille is derived from Middle High German kegel (“club”), from Old High German kegil, from Proto-West Germanic *kagil (“pile, pole, stake; peg, pin”), from *kagō (“bush, shrub”) + *-il (diminutive suffix).
