A foreign youth rounds Cape in the raw (6)
I believe the answer is:
unclad
'the raw' is the definition.
(thesaurus)
'a foreign youth rounds cape' is the wordplay.
'a foreign' becomes 'un' ('a' translated into French).
'youth' becomes 'lad' (I've seen this before).
'rounds' is an insertion indicator.
'cape' becomes 'c' (abbreviation used on maps).
'un'+'lad'='unlad'
'unlad' enclosing 'c' is 'UNCLAD'.
'in' acts as a link.
(Other definitions for unclad that I've seen before include "Uncovered" , "nude" , "Not dressed" , "Naked" , "In one's birthday suit" .)
