The thing you shouldn't have as furniture in a room? (7)
I believe the answer is:
whatnot
'room?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'the thing you shouldn't have as furniture in a' is the wordplay.
I cannot quite see how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
'a' could be 'an' and 'an' is located in the leftover letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for whatnot that I've seen before include "Bric-a-brac stand" , "Portable ornament stand" , "Thingummy - display stand" , "Thingumajig" , "part of the furniture" .)
