Regret street in Paris (3)
I believe the answer is:
rue
I believe this is a double definition.
'regret' is the first definition.
(to rue something is to regret it)
'street in paris' is the second definition.
('street' in French)
(Other definitions for rue that I've seen before include "Feel bad" , "Bitter-tasting herb" , "Regret in a French street" , "Feel sorry" , "Regret the bitter herb" .)
