German song wasn't true (4)
I believe the answer is:
lied
I believe this clue is a double definition.
'german song' is the first definition.
('song' in German)
'wasn't true' is the second definition.
(I've seen this in another clue)
(Other definitions for lied that I've seen before include "piece of music" , "German art song" , "Told an untruth" , "Made up a story" , "Told untruths; song" .)
