The impressions provided by one's belongings? (7)
I believe the answer is:
effects
This might be a double definition.
'the impressions' is the first definition.
(effect is a kind of impression)
'one's belongings' is the second definition.
'effects' can be an answer for 'belongings' (I've seen this before). I'm not sure about the 'one's' bit.
'provided by' is the link.
Can you help me to learn more?
(Other definitions for effects that I've seen before include "one's luggage" , "Total possessions" , "Personal property - results" , "Consequences or possessions" , "goods" .)
