A flat region around Brazil associated with a fair amount of dramas (6)
I believe the answer is:
tundra
'fair amount of dramas' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'a flat region around brazil associated with a' is the wordplay.
'a flat region' becomes 'dr' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'around' says the letters should be written backwards.
'brazil' becomes 'nut' (I've seen this in another clue).
'associated with' says to put letters next to each other.
'nut' in reverse letter order is 'tun'.
'dr' put after 'tun' is 'tundr'.
'tundr'+'a'='TUNDRA'
Can you help me to learn more?
(Other definitions for tundra that I've seen before include "Cold plain" , "Vast flat treeless zone" , "Treeless frozen Arctic plain" , "Vast treeless plane" , "Vast level Arctic regions with frozen subsoil" .)
