Provide German organ (7)
I believe the answer is:
deliver
'provide' is the definition.
(thesaurus)
'german organ' is the wordplay.
'german' becomes 'de' (language code).
'organ' becomes 'liver' (liver is a kind of organ).
'de'+'liver'='DELIVER'
(Other definitions for deliver that I've seen before include "Set free, provide" , "Bring to a destination and hand over" , "Supply, hand over" , "Hand over (letter)" , "bear" .)
