German order for cab (6)
I believe the answer is:
hansom
'for cab' is the definition.
(I've seen this before)
'german order' is the wordplay.
'german' becomes 'Hans' (common German name).
'order' becomes 'om' (Order of Merit).
'hans'+'om'='HANSOM'
(Other definitions for hansom that I've seen before include "One-horse cab" , "Victorian cab" , "Type of cab" , "Two-wheeled one-horse carriage" , "Two-wheeled horse-drawn covered cab" .)
