Sloshed Stan harbours good or bad feeling (5)
I believe the answer is:
angst
'bad feeling' is the definition.
'Angst' can be an answer for 'feeling' (Angst is an example). I'm not sure about the 'bad' bit.
'sloshed stan harbours good' is the wordplay.
'sloshed' is an anagram indicator.
'harbours' means one lot of letters goes inside another.
'good' becomes 'g' (abbreviation).
'stan' with letters rearranged gives 'anst'.
'anst' placed around 'g' is 'ANGST'.
'or' acts as a link.
Can you help me to learn more?
(Other definitions for angst that I've seen before include "Acute, but unspecific, feeling of anxiety" , "Acute sense of remorse" , "General feeling of anxiety" , "Nagging worry" , "Philosophical unease" .)
