Silver found in case on a temple (6)
I believe the answer is:
pagoda
'temple' is the definition.
(pagoda is a kind of temple)
'silver found in case on a' is the wordplay.
'silver' becomes 'ag' ('Ag' can be a synonym of 'silver').
'found in' indicates putting letters inside.
'case' becomes 'pod' (pod is a kind of case**).
'on' means one lot of letters go next to another.
'ag' put inside 'pod' is 'pagod'.
'pagod'+'a'='PAGODA'
(Other definitions for pagoda that I've seen before include "Hindu temple shaped like pyramid" , "Pyramid-shaped Hindu temple" , "Temple - a GPO ad (anag)" , "A buddhist temple built in tiers" , "temple? Quite the opposite" .)
