Where holidaymakers have somewhere to swim, note (5)
I believe the answer is:
poole
'where holidaymakers have somewhere to swim' is the definition.
The definition suggests a singular noun which matches the answer.
'note' is the wordplay.
I cannot really see how this works, but
'note' could be 'e' (musical note) and 'e' is found within the answer.
The remaining letters 'pool' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for poole that I've seen before include "Town near Bournemouth" , "Dorset resort, harbour" , "Port in Dorset" , "Resort near Bournemouth" , "Place in Dorset" .)
