Suits and trunks (5)
I believe the answer is:
cases
This clue could be a double definition.
'suits' is the first definition.
('case' can be a synonym of 'suit')
'trunks' is the second definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps you can see an association between them that I don't see?
'and' acts as a link.
Can you help me to learn more?
(Other definitions for cases that I've seen before include "Clothes containers or court trials" , "Lawsuits or pieces of luggage" , "Pieces of luggage and legal proceedings" , "patients" , "Instances; containers" .)
