Country areas provide setting for long break (6)
I believe the answer is:
angola
'country' is the definition.
(Angola is an example)
'provide setting for long break' is the wordplay.
'provide' becomes 'aa' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'setting for' means one lot of letters goes inside another (inserted letters are set inside others).
'break' indicates anagramming the letters.
'long' with letters rearranged gives 'ngol'.
'aa' enclosing 'ngol' is 'ANGOLA'.
'areas' acts as a link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for angola that I've seen before include "It's no gala in this African country" , "African state (and Department of Health?)" , "Southwestern African state" , "SW African country" , "South-west African country, capital Luanda" .)
