Supermarket has no parking, can you believe it? (3)
I believe the answer is:
coo
'you believe it?' is the definition.
I can't tell whether this definition defines the answer.
'supermarket has no parking' is the wordplay.
'supermarket' becomes 'Co-op' (The Co-operative).
'has no' indicates named letters should be taken away.
'parking' becomes 'p' (abbreviation on road signs).
'coop' with 'p' removed is 'COO'.
'can' is the link.
Can you help me to learn more?
(Other definitions for coo that I've seen before include "Bill and I go together" , "Pigeon's sound" , "it's surprising!" , "Bill's companion" , "Pigeon noise" .)
