No TV clergyman is famous (5)
I believe the answer is:
noted
'famous' is the definition.
(noted can mean well-known or famous)
'no tv clergyman' is the wordplay.
'tv clergyman' becomes 'ted' (I can't justify this - if you can you should give a lot more credence to this answer).
'no'+'ted'='NOTED'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for noted that I've seen before include "saw" , "Celebrated or recorded" , "Remarked - famous" , "prominent" , "Significant" .)
