Piece of furniture and part of trunk belonging to some artists (5,2,7)
I believe the answer is:
chest of drawers
'piece of furniture' is the definition.
(chest of drawers is a kind of piece of furniture)
'part of trunk belonging to some artists' is the subsidiary indication.
'part of trunk' becomes 'chest' ('chest' is part of 'trunk').
'belonging to' becomes 'of' (I've seen this in other clues).
'some artists' becomes 'drawers' (drawer is a kind of artist**).
'chest'+'of'+'drawers'='chestofdrawers'
'and' is the link.
(Other definitions for chest of drawers that I've seen before include "Piece of furniture" , "storage unit" , "clothing unit" , "may have a lot of clothes" , "where personal items may be kept" .)
