Seeking enjoyment in grand old city: 'Coot's Touring Society' (9)
I believe the answer is:
epicurism
'seeking enjoyment' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'grand old city coot's touring society' is the wordplay.
'grand' becomes 'epic' (I've seen this in another clue).
'old city' becomes 'ur' (ancient city state).
'coot's' becomes 'I'm' (I am - where the crossword setter is 'Coot').
'touring' means one lot of letters goes inside another (tour can mean to go around).
'society' becomes 's' (common abbreviation in names of organisations).
'im' going around 's' is 'ism'.
'epic'+'ur'+'ism'='EPICURISM'
'in' is the link.
Can you help me to learn more?
(Another definition for epicurism that I've seen is " Love of fine food".)
