Distinguishing features for flat, shallow containers, I hear (6)
I believe the answer is:
traits
'distinguishing features' is the definition.
(I've seen this in another clue)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for traits that I've seen before include "Artist (anag.)" , "Features or qualities that distinguish someone's character" , "Characteristics, distinguishing qualities" , "Distinguishing features" , "Identifying characteristics" .)
