Little time lost amongst all that apprehension (5)
I believe the answer is:
angst
'apprehension' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for angst that I've seen before include "Feeling of guilt or remorse" , "Acute, but unspecific, feeling of anxiety" , "Oppressive feeling of worry, guilt" , "Apprehension" , "General feeling of dread" .)
