Removal from Eden, toil being involved (8)
I believe the answer is:
deletion
'removal' is the definition.
(deletion is a kind of removal)
'eden toil being involved' is the wordplay.
'being involved' indicates an anagram (involved can mean confusing or complex).
'eden'+'toil'='edentoil'
'edentoil' with letters rearranged gives 'DELETION'.
'from' acts as a link.
(Other definitions for deletion that I've seen before include "Process of erasure" , "Idle note (anag) - erasure" , "shelving" , "A crossing out of noted lie" , "Removal (of text)" .)
