Somewhat paranoid about where Scots live (4)
I believe the answer is:
iona
'where scots live' is the definition.
(Scottish island)
'somewhat paranoid about' is the wordplay.
'somewhat' says the answer is hidden in the clue.
'about' says the letters should be written backwards.
'anoi' is hidden in the letters of 'paranoid'.
'anoi' written backwards gives 'IONA'.
(Other definitions for iona that I've seen before include "inch" , "island off Scotland" , "Greek sea god" , "place in the Hebrides" , "Scottish land known for St Columba" .)
