In the south of France study is not expected (6)
I believe the answer is:
sudden
'expected' is the definition.
Both the definition and answer are adjectives. Maybe there's a link between them I don't understand?
'in the south of france study is not' is the wordplay.
I cannot quite understand how this works, but
'south' could be 's' (abbreviation) and 's' is present in the answer.
'study' could be 'den' (term for a study or office) and 'den' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for sudden that I've seen before include "Quickly, without notice or warning" , "Immediate and surprising" , "Done unexpectedly" , "Unexpected, without warning" , "Rapid and unexpected" .)
