New organisation takes blame for cover up (6)
I believe the answer is:
enwrap
'cover up' is the definition.
'enwrap' can be an answer for 'cover' (enwrapping is a kind of covering). I'm not certain of the 'up' bit.
'new organisation takes blame' is the wordplay.
'organisation' indicates anagramming the letters.
'takes' says to put letters next to each other.
'blame' becomes 'rap' (synonyms).
'new' with letters rearranged gives 'enw'.
'enw'+'rap'='ENWRAP'
'for' is the link.
Can you help me to learn more?
(Other definitions for enwrap that I've seen before include "Envelop, enfold" , "put in package" , "Absorb" , "Cover (with paper, etc)" , "Cover completely" .)
