Czech State control (8)
I believe the answer is:
restrain
'czech state control' is the definition.
'restrain' can be an answer for 'control' (I've seen this before). I'm not certain of the 'czech state' bit.
'czech state control' is the wordplay.
'czech state' becomes 'res' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'control' becomes 'train' (training is a kind of controlling).
'res'+'train'='RESTRAIN'
Can you help me to learn more?
(Other definitions for restrain that I've seen before include "Arrest - confine - subdue" , "stay" , "Keep under control" , "Stop" , "In arrest (anagram)" .)
