He for one must be supported by church and state (9)
I believe the answer is:
pronounce
'state' is the definition.
(thesaurus)
'he for one must be supported by church' is the wordplay.
I cannot really understand how this works, but
'he' could be 'pronoun' ('he' is a pronoun) and 'pronoun' is present in the answer.
'church' could be 'ce' (Church of England) and 'ce' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for pronounce that I've seen before include "Make the sound of (word)" , "Articulate in a certain way" , "Articulate - judge" , "make a declaration" , "Declare, announce" .)
