Have the bloke call for the wrapper (8)
I believe the answer is:
'the wrapper' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'have the bloke call' is the wordplay.
'have the bloke' becomes 'cove' (I can't explain this - if you can you should give a lot more credence to this answer).
'call' becomes 'ring' (telephone call).
'for' is the link.
Can you help me to learn more?
(Other definitions for covering that I've seen before include "Protecting" , "shelter" , "Sleeve" , "Enveloping" , "acting as a reporter" .)
