Uncivilised local lawyers, many naked on island (9)
I believe the answer is:
barbarian
'uncivilised' is the definition.
(I know that uncivilised can be written as barbarian)
'local lawyers many naked on island' is the wordplay.
'local' becomes 'bar' (local can mean someone's local pub).
'lawyers' becomes 'bar' (the bar can mean the legal profession).
'naked' says to take the centre (outside letters removed so centre is unclothed).
'on' is a charade indicator (letters next to each other).
'island' becomes 'i' (geographical abbreviation).
The middle letters of 'many' are 'an'.
'an' put after 'i' is 'ian'.
'bar'+'bar'+'ian'='BARBARIAN'
(Other definitions for barbarian that I've seen before include "Savage - rugby player" , "outlandish foreigner" , "Uncultured, brutish" , "Uncivilised - Goth" , "Brutish type" .)
