Ordinary brown rolls, characteristic of country life, unopened (7)
I believe the answer is:
natural
'ordinary' is the definition.
(I've seen this before)
'brown rolls characteristic of country life unopened' is the wordplay.
'brown rolls characteristic' becomes 'nat' (I can't justify this - if you can you should give a lot more credence to this answer).
'of country life' becomes 'rural' (I've seen this before).
'unopened' means to remove the first letter (without opening letter).
'rural' with its first letter taken away is 'ural'.
'nat'+'ural'='NATURAL'
Can you help me to learn more?
(Other definitions for natural that I've seen before include "Not synthetic or man-made" , "Normal - genuine" , "Not made, normal" , "Fuel from underground" , "Inborn; unaffected" .)
