Pass the cockney as well (4)
I believe the answer is:
hand
'pass' is the definition.
(I know that pass can be written as hand)
'cockney as well' is the wordplay.
'cockney' becomes 'h' (I can't explain this - if you can you should give a lot more credence to this answer).
'as well' becomes 'and' (I've seen this in other clues).
'h'+'and'='HAND'
'the' is the link.
Can you help me to learn more?
(Other definitions for hand that I've seen before include "Help < and applause" , "Pointer; workman" , "See 12" , "Limb extremity" , "Worker - four inches - bunch of bananas" .)
