Grace, with glee, swishes the cane, flourishing it (8)
I believe the answer is:
elegance
'grace' is the definition.
(I've seen this in another clue)
'with glee swishes the cane flourishing it' is the wordplay.
'with' indicates putting letters inside.
'glee swishes' becomes 'leg' (I can't explain this - if you can you should give a lot more credence to this answer).
'flourishing' is an anagram indicator (letters grow or flourish differently).
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'cane' is an anagram of 'eanc'.
'leg' inserted within 'eanc' is 'eleganc'.
'eleganc'+'e'='ELEGANCE'
Can you help me to learn more?
(Other definitions for elegance that I've seen before include "Gracefulness" , "Style; refinement" , "Showing good taste in dress or style" , "Refinement, polish" , "Refinement - grace" .)
