Silver rig-out on girl is wrong (8)
I believe the answer is:
aggrieve
'wrong' is the definition.
(aggrieving is a kind of wronging)
'silver rig-out on girl' is the wordplay.
'silver' becomes 'ag' (Ag is the chemical symbol for silver).
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'on' is an insertion indicator (as in clothing \'on\' a person).
'girl' becomes 'eve' (**).
'rig' anagrammed gives 'gri'.
'ag' going into 'gri' is 'aggri'.
'aggri'+'eve'='AGGRIEVE'
'is' acts as a link.
(Other definitions for aggrieve that I've seen before include "Distress, afflict" , "Make resentful" , "Cause annoyance to" , "Pain or injure" , "Cause offence or injury to" .)
