Furniture contains trunk filled with old underwear (5,2,7)
I believe the answer is:
chest of drawers
'furniture' is the definition.
(chest of drawers is a kind of furniture)
'trunk filled with old underwear' is the wordplay.
I cannot really understand how this works, but
'trunk' could be 'chest' (I've seen this in another clue) and 'chest' is found in the answer.
'with' could be 'w' (abbreviation) and 'w' is present in the answer.
'old' could be 'o' (common abbreviation eg in OE for Old English) and 'o' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'contains' acts as a link.
Can you help me to learn more?
(Other definitions for chest of drawers that I've seen before include "may have a lot of clothes" , "where personal items may be kept" , "clothing unit" , "Storage furniture" , "storage unit" .)
