Clergyman turns up to entertain king with no clothes (5)
I believe the answer is:
naked
'no clothes' is the definition.
'clergyman turns up to entertain king' is the wordplay.
'clergyman' becomes 'dean' (dean is a kind of clergyman).
'turns up' shows that the letters should be reversed in order.
'to entertain' is an insertion indicator.
'king' becomes 'K' (chess abbreviation).
'dean' reversed gives 'naed'.
'naed' enclosing 'k' is 'NAKED'.
'with' acts as a link.
(Other definitions for naked that I've seen before include "unprotected" , "Without clothes" , "Au naturel" , "Without protection" , "Unclad" .)
