The tidiest street on the French Riviera? (6)
I believe the answer is:
nicest
'the tidiest' is the definition.
I can't judge whether this defines the answer.
'street on the french riviera?' is the wordplay.
'street' becomes 'st' (abbreviation).
'on' says to put letters next to each other.
'the french riviera?' becomes 'nice' (I am not sure about this - if you are sure you should believe this answer much more).
'st' after 'nice' is 'NICEST'.
Can you help me to learn more?
(Other definitions for nicest that I've seen before include "I scent in the most pleasant way" , "Sin etc (anag)" , "Most pleasing" , "Most pleasant or fine" , "Most appealing" .)
