The etymology of the name of the river Dommel in the Netherlands causes some serious difficulties. In fact it has up to now been seen as an unsolved problem. A new close examination of the oldest attestations, like Dudmala (AD 704), has resulted in a new analysis, viz. *dūd-mal-a in which dūd- means ‘folk’, mal- means ‘dingplaats’ and -a is the appellative for ‘water’ < *aχwa-: ‘running water near to a dingplaats’. The two first elements find their parallel in the German place name Detmold, traditionally considered as going back to Germanic *Þeud-maχla – 1263 detmalle, 783 theodmalli.
