The Parisian going to Missouri and New York could be fruity! (6)
I believe the answer is:
lemony
'fruity' is the definition.
Both the answer and definition are adjectives. Perhaps you can see a link between them that I can't see?
'the parisian going to missouri and new york' is the wordplay.
'the parisian' becomes 'le' (definite article in French).
'going to' says to put letters next to each other.
'missouri' becomes 'mo' (abbreviation for the US state).
'and' is a charade indicator (letters next to each other).
'new york' becomes 'ny'.
'le'+'mo'+'ny'='LEMONY'
'could be' is the link.
Can you help me to learn more?
(Another definition for lemony that I've seen is " -- Snicket, A Series of Unfortunate Events author".)
