dodu

Auguste Scheler cautiously suggests that it belongs "doubtless" to the Old French "dondé" from which "dondon" is derived, citing Diez who associates it with the Latin "dotatus" but dismissing this hypothesis in favor of the Frisian "dodd" ("block, mass") or the root "dod" of "dodiner" or "dodeliner", emphasizing that the plumpness causes a swaying motion.
