German style of feeding trough (6)
I believe the answer is:
manger
'feeding trough' is the definition.
(I've seen this before)
'german style' is the wordplay.
'style' indicates an anagram (style can mean to shape or design).
'german' with letters rearranged gives 'MANGER'.
'of' acts as a link.
(Other definitions for manger that I've seen before include "German (anag)" , "makeshift bed" , "Trough for horse or cattle food" , "Crib" , "Feeding trough (with 16?)" .)
