Stand, also metal (7)
I believe the answer is:
andiron
'stand' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'also metal' is the wordplay.
'also' becomes 'and' (both can mean in addition).
'metal' becomes 'iron' (iron is a metal).
'and'+'iron'='ANDIRON'
Can you help me to learn more?
(Other definitions for andiron that I've seen before include "Fireplace log supporter" , "One supports burning wood" , "Logs support" , "Fireplace metalwork" , "Firedog -- Odin ran (anag)" .)
