Nice weather here, cool in America (4)
I believe the answer is:
fine
'nice' is the definition.
(I've seen this before)
'weather here cool in america' is the wordplay.
I cannot really see how this works, but
'cool' could be 'in' ('in' can mean fashionable or cool) and 'in' is present in the answer.
The remaining letters 'fe' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for fine that I've seen before include "Sunny -- penalty" , "French brandy" , "Excellent - form of punishment" , "Money paid as penalty" , "Monetary penalty - that's splendid" .)
