Injure woman when grabbing silver (6)
I believe the answer is:
damage
'injure' is the definition.
(I know that injure is a kind of damage)
'woman when grabbing silver' is the wordplay.
'woman' becomes 'dame' (dame can mean a woman).
'when grabbing' means one lot of letters goes inside another (inserted letters are grabbed).
'silver' becomes 'Ag' (Ag is the chemical symbol for silver).
'dame' placed around 'ag' is 'DAMAGE'.
(Other definitions for damage that I've seen before include "Harm, impair" , "Impair, hurt" , "Impair and lower value" , "Mar" , "Harm; reparation" .)
