Étymologie (Anglais)

From earlier randon, from Middle English randoun, raundon, from Old French randon, from randir (“to run, gallop”) (whence French randonnée (“long walk, hike”)), from Frankish *randiju (“a run, race”) or Old Norse rend (“a run, race”), both from Proto-Germanic *randijō, from *rinnaną (“run”, verb), from Proto-Indo-European *(H)r̥-nw- (“to flow, move, run”). Cognate with Middle Low German uprinden (“to jump up”), Danish rende (“to run”). See run.
