Virginia finds cover acceptable (5)
I believe the answer is:
valid
'acceptable' is the definition.
(I've seen this before)
'virginia finds cover' is the wordplay.
'virginia' becomes 'va' (US state abbreviation).
'finds' says to put letters next to each other.
'cover' becomes 'lid' (lid is a kind of cover).
'va'+'lid'='VALID'
(Other definitions for valid that I've seen before include "Legally acceptable, unexpired" , "Legitimate" , "Sound and logical, also legal" , "Still legally acceptable" , "Well-founded" .)
