Constituency housing for Spanish coastal town (7)
I believe the answer is:
seaport
'spanish coastal town' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'constituency housing for' is the wordplay.
'constituency' becomes 'seat' (House of Commons seats represent constituencies).
'housing' is an insertion indicator.
'for' becomes 'por' (I can't explain this - if you can you should believe this answer much more).
'seat' placed around 'por' is 'SEAPORT'.
Can you help me to learn more?
(Other definitions for seaport that I've seen before include "Lisbon, for example" , "place on the coast" , "Sydney perhaps" , "access to drink" , "Town with deep-water harbour" .)
