Game delivery round wicket by English (9)
I believe the answer is:
bagatelle
'game' is the definition.
(bagatelle is a kind of game)
'delivery round wicket by english' is the wordplay.
'delivery' becomes 'ball' (ball is a kind of delivery).
'round' means one lot of letters goes inside another.
'wicket' becomes 'gate'.
'by' means one lot of letters go next to another.
'english' becomes 'e' (abbreviation).
'ball' going around 'gate' is 'bagatell'.
'bagatell'+'e'='BAGATELLE'
(Other definitions for bagatelle that I've seen before include "Board game - trifle" , "Trifling matter" , "piece, one for piano" , "Trifle - game with pins and balls" , "drop in the ocean!" .)
