Steal some silver objects (3)
I believe the answer is:
rob
'steal' is the definition.
(robbing is a kind of stealing)
'some silver objects' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'ROB' is hidden within 'silver objects'.
(Other definitions for rob that I've seen before include "Nick" , "Plunder" , "Steal or purloin" , "Steal from (someone)" , "Steal violently" .)
