Etymology

Formally dudeln ‎(“play monotone music, tootle”) +‎ Sack ‎(“sack, bag”). The former component is based on Czech and/or Polish dudy (“bagpipes”), also borrowed into early modern German as Dudei; it is uncertain, however, whether the verb dudeln is also derived from this Slavic noun or whether it is an older German word.
