Emotion extremely enjoyable in dance (7)
I believe the answer is:
feeling
'emotion' is the definition.
(I've seen this before)
'extremely enjoyable in dance' is the wordplay.
'extremely' suggests removing the centre (only the extremes of the word are used).
'in' is an insertion indicator.
'dance' becomes 'fling' (I've seen this before).
'enjoyable' with its middle removed is 'ee'.
'ee' put within 'fling' is 'FEELING'.
(Other definitions for feeling that I've seen before include "Sensation" , "Emotion; opinion" , "Sense, emotion" , "Sympathy" .)
