OT prophet endlessly pursuing king’s pleasure (6)
I believe the answer is:
relish
'pleasure' is the definition.
(I know that relish is a type of enjoyment)
'ot prophet endlessly pursuing king's' is the wordplay.
'ot' becomes 'e' (I can't justify this - if you can you should believe this answer much more).
'prophet' becomes 'Elisha' (Hebrew prophet).
'endlessly' says to take the centre (the ends of the words are removed).
'pursuing' says to put letters next to each other.
'king' becomes 'R' (abbreviation for rex, king in Latin).
The middle of 'elisha' is 'lish'.
'e'+'lish'='elish'
'elish' after 'r' is 'RELISH'.
Can you help me to learn more?
(Other definitions for relish that I've seen before include "Thoroughly enjoy" , "Really enjoy" , "Enjoy to the full" , "appetizer?" , "what goes on food" .)
