Rest in shredded section of newspaper (6)
I believe the answer is:
'section of newspaper' is the definition.
'insert' can be an answer for 'section' (insert is a kind of section). I am unsure of the 'of newspaper' bit.
'rest in shredded' is the wordplay.
'shredded' indicates an anagram.
'restin' is an anagram of 'INSERT'.
Can you help me to learn more?
(Other definitions for insert that I've seen before include "Put in; enclosure" , "Put something inside something else" , "Add in" , "Introduce, put in" , "place in the interior" .)
