Beer stocked by the German shopkeeper? (6)
I believe the answer is:
dealer
'shopkeeper?' is the definition.
(thesaurus)
'beer stocked by the german' is the wordplay.
'beer' becomes 'ale' (type of beer).
'stocked by' indicates putting letters inside.
'the german' becomes 'der' ('the' in German).
'ale' put inside 'der' is 'DEALER'.
(Other definitions for dealer that I've seen before include "Buyer and seller of goods" , "Trader; card player" , "Stockjobber" , "Card distributor" , "One who trades, perhaps on stock exchange" .)
