Show-stopper for fellow at home with beer (6)
I believe the answer is:
finale
'show-stopper' is the definition.
I can't tell whether this defines the answer.
'fellow at home with beer' is the wordplay.
'fellow' becomes 'f' (abbreviation - of a society etc.).
'at home' becomes 'in' (similar in meaning).
'with' is a charade indicator (letters next to each other).
'beer' becomes 'ale' (type of beer).
'f'+'in'+'ale'='FINALE'
'for' is the link.
Can you help me to learn more?
(Other definitions for finale that I've seen before include "Conclusion, end" , "Last part of something" , "Last section of a musical composition" , "Conclusion of a performance" , "Final section of a musical composition" .)
