... with asymmetry in small part? Show agreement in court (5)
I believe the answer is:
synod
'court' is the definition.
(thesaurus)
'with asymmetry in small part? show agreement' is the wordplay.
'with' means one lot of letters go next to another.
'asymmetry in small part?' becomes 'sy' (I am not sure about this - if you are sure you should believe this answer much more).
'show agreement' becomes 'nod' (I've seen this before).
'sy' next to 'nod' is 'SYNOD'.
'in' acts as a link.
(Other definitions for synod that I've seen before include "Council of clergy to discuss policy" , "Ecclesiastical council" , "Church council" , "group of clergymen" , "Ecumenical council" .)
