Family endlessly raised capital (4)
I believe the answer is:
lima
'capital' is the definition.
(Lima is an example)
'family endlessly raised' is the wordplay.
'endlessly' says to take the centre (the ends of the words are removed).
'raised' says the letters should be written in reverse.
The middle letters of 'family' are 'amil'.
'amil' reversed gives 'LIMA'.
(Other definitions for lima that I've seen before include "Edible bean; capital city" , "South American capital" , "Mail to Peru'd capital" , "Mail it to Peruvian city" , "Mail to capital of Peru" .)
