The story
- Proto-Indo-European · derived from*av-“watercourse”
- Old Saxon · derived fromOsnabrugga
- German · derived fromOsnabrück
- English todayOsnabrück
From German Osnabrück, from Old Saxon Osnabrugga (literally “bridge of the Osna”), an old name for the river Hase. This name goes back to an earlier *Ausana, an older Pre-Germanic name for the river, said to be an Old European hydronym, ultimately from Proto-Indo-European *av- (“watercourse”), extended with -s. However, compare Proto-Germanic *ausaną (“to scoop up”), from Proto-Indo-European *h₂ews-. Doublet of osnaburg.
