You'll see quickly that it has a North End (7)
I believe the answer is:
preston
'you'll' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'quickly that it has a north end' is the wordplay.
I cannot quite see how this works, but
'quickly' could be 'presto' (I've seen this before) and 'presto' is found within the answer.
'north' could be 'n' (abbreviation) and 'n' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'see' is the link.
Can you help me to learn more?
(Other definitions for preston that I've seen before include "Town in Lancashire" , "town in northern England" , "City in Lancashire" , "Town on the Ribble" , "Administrative centre of Lancashire" .)
