Left in Paris? That's awkward! (6)
I believe the answer is:
gauche
I believe this clue is a double definition.
'left in paris?' is the first definition.
('left' in French)
'awkward' is the second definition.
(I've seen this before)
'that's' acts as a link.
(Other definitions for gauche that I've seen before include "Clumsy and inept" , "Awkward, inept" , "Raw and naive" , "Socially awkward or tactless" , "Awkward - ill-bred" .)
