Reportedly amend sacrifice location (5)
I believe the answer is:
altar
'sacrifice location' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'reportedly amend' is the wordplay.
'reportedly' shows a homophone (sound like).
'amend' becomes 'alter' (I've seen this before).
'alter' sounds like 'ALTAR'.
Can you help me to learn more?
(Other definitions for altar that I've seen before include "Site of worship" , "Sacrifical stone sounds as if it will change" , "Focus of religious activity" , "Table used for the mass or eucharist" , "Sacrificial structure" .)
