Row about US state going in for such trickery! (7)
I believe the answer is:
evasion
'trickery' is the definition.
(thesaurus)
'row about us state going in' is the wordplay.
I cannot really understand how this works, but
'about' could be 'on' (as in a book 'on' a certain topic) and 'on' is found in the answer.
'state' could be 'va' and 'va' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'for such' acts as a link.
Can you help me to learn more?
(Other definitions for evasion that I've seen before include "Avoidance; equivocation" , "Hedging" , "Fencing" , "Deceptive action" , "A dodgy answer or excuse" .)
