At home, received block of metal (5)
I believe the answer is:
ingot
'block of metal' is the definition.
('ingot' can be a synonym of 'block of metal')
'at home received' is the wordplay.
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'received' becomes 'got' ('get' can be a synonym of 'receive').
'in'+'got'='INGOT'
(Other definitions for ingot that I've seen before include "Block (of steel, gold, etc)" , "Mass of cast metal" , "Block of, eg, gold" , "Block of precious metal" , "Mass of unwrought gold, for instance" .)
