Herb – French street (3)
I believe the answer is:
rue
I believe this clue is a double definition.
'herb' is the first definition.
(rue is a herb)
'french street' is the second definition.
(French for street or road)
(Other definitions for rue that I've seen before include "way Parisians go about" , "Regret in a French street" , "Regret the bitter herb" , "Regret or repent" , "Cry" .)
