The clergy have point in dress (6)
I believe the answer is:
clothe
'dress' is the definition.
(I know that dress can be written as clothe)
'the clergy have point' is the wordplay.
'the clergy' becomes 'cloth' (I've seen this before).
'have' says to put letters next to each other.
'point' becomes 'e' (compass point).
'cloth'+'e'='CLOTHE'
'in' acts as a link.
(Other definitions for clothe that I've seen before include "Equip" , "Remote area in Mongolia/China" , "Provide with garments" , "Put garments onto" , "Dress (someone)" .)
