Entreaties to dance. No head for enjoyment (9)
I believe the answer is:
pleasance
'no head for enjoyment' is the definition.
The answer and definition can be both feelings as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'entreaties to dance' is the wordplay.
'entreaties' becomes 'pleas' (plea is a kind of entreaty).
'to' says to put letters next to each other.
'dance' becomes 'ance' (I can't explain this - if you can you should give a lot more credence to this answer).
'pleas'+'ance'='PLEASANCE'
Can you help me to learn more?
(Other definitions for pleasance that I've seen before include "Sane place (anag.)" , "secluded spot" , "Secluded part of garden" , "secret garden" .)
