Old province seen in German journal (5)
I believe the answer is:
anjou
'old province' is the definition.
(I've seen this before)
'in german journal' is the wordplay.
'in' indicates a hidden word.
'ANJOU' is hidden in the letters of 'german journal'.
'seen' is the link.
(Other definitions for anjou that I've seen before include "Old French province" , "Whence Angevins came" , "Province formerly" , "Old province of the Loire valley, an English possession 1154-1204" , "Historic French province" .)
