Feel remorse, the French way (3)
I believe the answer is:
rue
This clue is a double definition.
'feel remorse' is the first definition.
(I've seen this in another clue)
'french way' is the second definition.
('road' or 'street' in French)
'the' acts as a link.
(Other definitions for rue that I've seen before include "Plant producing oil" , "show regret" , "Deplore" , "Fish eggs" , "Feel bad" .)
