Game bird clipped, quiet one escapes (7)
I believe the answer is:
croquet
'game bird' is the definition.
'croquet' can be an answer for 'game' (I've seen this before). I'm not certain of the 'bird' bit.
'clipped quiet one escapes' is the wordplay.
'clipped' becomes 'cro' (I can't justify this - if you can you should give a lot more credence to this answer).
'one' becomes 'i' (Roman numeral).
'escapes' suggests deleting specific letters.
'quiet' with 'i' taken out is 'quet'.
'cro'+'quet'='CROQUET'
Can you help me to learn more?
(Other definitions for croquet that I've seen before include "Game in which a wooden ball is hit through hoops" , "... or possibly at this ball game" , "Game which involves driving balls through hoops" , "Mallet and hoop game" , "Game with wooden balls, mallets and hoops" .)
