Palindromic German name (4)
I believe the answer is:
otto
'palindromic german name' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for otto that I've seen before include "-- Klemperer, conductor" , "Swiss perhaps" , "Reversible German" , "Palindromic German male Christian name" , "Male German name - a palindrome" .)
