Row backed about Virginia's prevarication (7)
I believe the answer is:
evasion
'prevarication' is the definition.
(synonyms)
'row backed about virginia's' is the wordplay.
'row' becomes 'noise' (I've seen this before).
'backed' is a reversal indicator.
'about' indicates putting letters inside.
'virginia' becomes 'va' (US state abbreviation).
'noise' back-to-front is 'esion'.
'esion' placed around 'va' is 'EVASION'.
(Other definitions for evasion that I've seen before include "attempt to withhold truth?" , "The act of dodging the issue." , "deception" , "Fencing" , "Hedging" .)
