köken: Deverbal of créner (“to kern”), from crenedes (“notched”), from Vulgar Latin *crinare, probably of Celtic/Gaulish origin, from Proto-Celtic *krini-, from Proto-Indo-European *krey- (“to divide, separate”). Or, less likely, from Latin cernō (“to separate”), itself from the same root.
aile: cran d'arrêt, être à cran, monter d'un cran
Ce garçon a du cran, pour oser sauter en parachute.
köken: Possibly from garfa (“animal's claw”), from Andalusian Arabic جَارْفَا (gārfā, “handful”), from Arabic غُرْفَة (ḡurfa, “cup or dipper”), from غَرَفَ (ḡarafa, “to ladle”), with influence from garfio (“hook”). Or, possibly from Vulgar Latin *garra, from Gaulish *garrā (“leg”) (compare Breton gar, Old Irish gairri (“calves”)), from Proto-Celtic *garros; see Cornish garr.
