To glide around at height gives great pleasure (7)
I believe the answer is:
delight
'great pleasure' is the definition.
(I've seen this before)
'to glide around at height' is the wordplay.
I cannot really see how this works, but
an anagram of 'glide' is 'delig' which is present in the answer.
'height' could be 'ht' (abbreviation) and 'ht' is found within the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
'gives' acts as a link.
Can you help me to learn more?
(Other definitions for delight that I've seen before include "Rejoice" , "Greatly please" , "Give great pleasure to" , "Captivate" , "Gladden" .)
