German moved down and frowned (8)
I believe the answer is:
glowered
'frowned' is the definition.
('glower' can be a synonym of 'frown')
'german moved down' is the wordplay.
'german' becomes 'g' (abbreviation).
'moved down' becomes 'lowered' (I've seen this in another clue).
'g'+'lowered'='GLOWERED'
'and' acts as a link.
(Other definitions for glowered that I've seen before include "Stared angrily" , "Looked furious" , "Showed disapproval" , "Scowled" .)
