One who will feel at home in Madrid - and Paris, perhaps (8)
I believe the answer is:
spaniard
'one who will feel at home in madrid' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'and paris perhaps' is the wordplay.
'perhaps' indicates an anagram.
'and'+'paris'='andparis'
'andparis' with letters rearranged gives 'SPANIARD'.
Can you help me to learn more?
(Other definitions for spaniard that I've seen before include "European national" , "Malaga man or woman, perhaps?" , "Eg, a native of Madrid" , "A native of Iberian country" , "Slope-measuring instrument" .)
