From Proto-Germanic *dreuzaz, *drauziz, from Proto-Indo-European *dʰrews- (“to break, break off, crumble”). Cognate with Old Saxon drōr, Old High German trōr, and Old Norse and Icelandic dreyri. The historical sense is of something which ‘falls’: the Germanic base is also the source of Old English drēosan (“fall”).
- gore, blood
- Iċ his blōd āġēat, drēor on eorðan.
- I spilled his blood, his gore on the earth.
