Residence of a German man of law (5)
I believe the answer is:
abode
'residence' is the definition.
(synonyms)
'a german man of law' is the wordplay.
'german man of law' becomes 'Bode' (astronomer Johann Bode, as in Titius-Bode law).
'a'+'bode'='ABODE'
'of' acts as a link.
(Other definitions for abode that I've seen before include "stay" , "Dwelling, residence" , "Home or domicile" , "Pad" , "Place of residence" .)
