Silver ____ (6)
'silver' is the definition.
(I know that silver can be written as argent)
This is all the clue.
(Other definitions for argent that I've seen before include "Silver on a coat of arms" , "Tincture of silver in heraldry" , "Silver in 1 Down" , "Heraldic silver in garnet" , "White" .)
(Other definitions for screen that I've seen before include "Show a motion picture (of)" , "Protect or conceal" , "Examine methodically" , "Guard" , "Movable partitions" .)
