Exaggeration appears to suit the countrys rulers to a T (13)
I believe the answer is:
overstatement
'exaggeration' is the definition.
(I know that exaggeration can be written as overstatement)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for overstatement that I've seen before include "Exaggeration" , "Hyperbole" .)
