Home acquired metallic bar? (5)
I believe the answer is:
ingot
'metallic bar?' is the definition.
(I've seen this before)
'home acquired' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'acquired' becomes 'got' ('get' can be a synonym of 'acquire').
'in'+'got'='INGOT'
(Other definitions for ingot that I've seen before include "Cast metal obtained from a mould" , "valuable block" , "A brick shaped lump of gold" , "Unwrought metal cast in a mould" , "Cast metal brick" .)
