To be left in Paris is awkward (6)
I believe the answer is:
gauche
This clue is a double definition.
'to be left in paris' is the first definition.
('left' in French)
'awkward' is the second definition.
(I've seen this before)
'is' acts as a link.
(Other definitions for gauche that I've seen before include "Lacking grace" , "Lacking ease of manner (from the French)" , "Unsophisticated and socially awkward" , "Awkward in manner, tactless" , "left for Paris" .)
