Fortunate Frenchman goes to Kentucky (5)
I believe the answer is:
lucky
'fortunate' is the definition.
(similar in meaning)
'frenchman goes to kentucky' is the wordplay.
'frenchman goes' becomes 'luc' (I can't explain this - if you can you should give a lot more credence to this answer).
'to kentucky' becomes 'ky' (abbreviation).
'luc'+'ky'='LUCKY'
Can you help me to learn more?
(Other definitions for lucky that I've seen before include "Auspicious" , "Game where prizes are picked from a tub" , "Bringing good fortune" , "by chance" , "having the rub of the green?" .)
