Takes exception to material things (7)
I believe the answer is:
objects
'material things' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for objects that I've seen before include "Opposes" , "Articles; aims" , "Material things" , "Expresses opposition" , "Takes exception to the things?" .)
