Lovebirds at heart want somewhere to swim in resort (9)
I believe the answer is:
blackpool
'swim in resort' 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?
'lovebirds at heart want somewhere' is the wordplay.
I cannot really understand how this works, but
'want' could be 'lack' (synonyms) and 'lack' is present in the answer.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for blackpool that I've seen before include "Lancashire resort" , "Northern football team" .)
