Spirit shown by brother Andrew (6)
I believe the answer is:
brandy
'spirit' is the definition.
(I've seen this before)
'shown by brother andrew' is the wordplay.
'shown by' is a charade indicator (letters next to each other).
'brother' becomes 'br'.
'andrew' becomes 'andy'.
'br' next to 'andy' is 'BRANDY'.
(Other definitions for brandy that I've seen before include "Strong alcoholic spirit" , "Hero's drink of choice?" , "Cognac, perhaps" , "eg Armagnac" , "Strong alcohol" .)
