English cricket side finally win in great style (8)
I believe the answer is:
elegance
'style' is the definition.
(I've seen this before)
'english cricket side finally win in great' is the wordplay.
'english' becomes 'e' (abbreviation).
'cricket side' becomes 'leg' (I've seen this before).
'finally' indicates one should take the final letters.
'in' indicates putting letters inside.
'great' becomes 'ace' (ace can informally mean very good).
The final letter of 'win' is 'n'.
'n' inserted into 'ace' is 'ance'.
'e'+'leg'+'ance'='ELEGANCE'
(Other definitions for elegance that I've seen before include "Fine quality" , "Gracefulness" , "Grace and stylishness" , "Grace, style" , "Refinement - grace" .)
