Picked up change in place of worship (5)
I believe the answer is:
altar
'place of worship' is the definition.
(I've seen this before)
'picked up change' is the wordplay.
'picked up' shows a homophone (sound like).
'change' becomes 'alter' (altering is a kind of changing).
'alter' is a homophone of 'ALTAR'.
'in' acts as a link.
(Other definitions for altar that I've seen before include "Sacrificial structure" , "where sacrifices are made" , "Table for sacrifice" , "Consecrated table in church" , "High table for religious ceremonies" .)
