Feel horrible about the French way (3)

I believe the answer is:

rue

I'm a little stuck... Click here to teach me more about this clue!

'french way' is the definition.
('road' or 'street' in French)

I don't understand the rest of the clue.

(Other definitions for rue that I've seen before include "At one time, pity" , "show regret" , "Regret - wild shrub" , "show you're sorry!" , "Be regretful" .)

I've seen this clue in The Times.
