The are the possible connections we may consider:
- The name of an Ásynja, Valkyrja, amd personal name Þrúðr and the noun þrúðr, the French name Gertrude, Gertraud, Osþryþ, Ásþrúðr
- The Old English verb þreotan
- The German adjective traut
- The verbs tread and trod, Gothic trudan, Old English noun trodu, Old Norse noun átroð
The Germanic d- often changes to t- in German: treiben, Tracht, Tag, Tür, trinken, etc. However, there are exceptions: denken, dunkel, dumm, Draht, durch, deutsch, drehen, etc. The Germanic þ- may therefore correspond to German t or d.
The Germanic long u changes to au in German, but it remains ū in Swiss German.
