Teutonic war god (5)
I believe the answer is:
wotan
'teutonic war god' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for wotan that I've seen before include "Another name for Odin" , "Germanic god" , "Teutonic god in the Ring Cycle" , "Supreme god" , "Wagnerian head god" .)
