To glide around at height gives great pleasure (7)
I believe the answer is:
delight
'great pleasure' is the definition.
(I've seen this in another clue)
'to glide around at height' is the wordplay.
I cannot really understand 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 in the answer.
No letters remain.
This explanation may well be incorrect...
'gives' is the 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" .)
