Where a cab turns up, near Manchester (5)
I believe the answer is:
bacup
'where a' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'cab turns up near manchester' is the wordplay.
I cannot really see how this works, but
an anagram of 'cab' is 'bac' which is present in the answer.
'up' is within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for bacup that I've seen is " Lancashire town".)
