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 cannot judge whether it can be defined by this definition.
'cab turns up near manchester' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'cab' is 'bac' which is located in the answer.
'up' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for bacup that I've seen is " Lancashire town".)
