French left without social skills (6)
I believe the answer is:
gauche
I believe this clue is a double definition.
'french left' is the first definition.
('left' in French)
'without social skills' is the second definition.
(gauche can mean socially awkward or inept)
(Other definitions for gauche that I've seen before include "Tactless - blundering" , "Hug ace, being socially awkward" , "Awkward, inept" , "'Lacking social polish, awkward (6)'" , "left for Paris" .)
