City seen travelling north from Spain? (4)
I believe the answer is:
pisa
'city' is the definition.
(Pisa is an example)
'travelling north from spain?' is the wordplay.
'travelling' is an anagram indicator.
'north' becomes 'n' ('N' can be a synonym of 'north').
'from' is a deletion indicator.
'spain' with 'n' removed is 'spai'.
'spai' is an anagram of 'PISA'.
'seen' is the link.
(Other definitions for pisa that I've seen before include "Tuscan city" , "Italian city with leaning tower" , "City with listed building" , "City in Tuscany" , "Location of leaning tower" .)
