Accepted a rush after silver (6)
I believe the answer is:
agreed
'accepted' is the definition.
(agreeing is a kind of accepting)
'a rush after silver' is the wordplay.
'a rush' becomes 'reed' (I've seen this in other clues).
'after' says to put letters next to each other.
'silver' becomes 'Ag' (Ag is the chemical symbol for silver).
'reed' after 'ag' is 'AGREED'.
(Other definitions for agreed that I've seen before include "Assented, acquiesced" , "OK, fine!" , "Accorded" , "Done!" , "came to the same conclusion" .)
