Senior clergyman has had meal and is now exhausted (6)
I believe the answer is:
beaten
'exhausted' is the definition.
(thesaurus)
'senior clergyman has had meal and is' is the wordplay.
'senior clergyman' becomes 'n' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'has' says to put letters next to each other.
'had meal' becomes 'ate' (to have a meal is to eat).
'and' says to put letters next to each other.
'is' becomes 'be'.
'ate' after 'be' is 'beate'.
'n' after 'beate' is 'BEATEN'.
'now' is the link.
Can you help me to learn more?
(Other definitions for beaten that I've seen before include "Describes a path much trodden" , "Defeated or mixed vigorously" , "Conquered" , "Failed to win - punished" , "Worsted" .)
