Miserable German left with hesitation (4)
I believe the answer is:
glum
'miserable' is the definition.
(I've seen this before)
'german left with hesitation' is the wordplay.
'german' becomes 'g' (abbreviation).
'left' becomes 'L' (common abbreviation).
'with' means one lot of letters go next to another.
'hesitation' becomes 'um' (um is said in hesitation).
'g'+'l'+'um'='GLUM'
(Other definitions for glum that I've seen before include "Doleful" , "Sullen-looking" , "Dejected, morose" , "Sad, down-in-th-mouth" , "Dispirited, moody" .)
