All things stemming from Eve's ruin (8)
I believe the answer is:
universe
'all' is the definition.
(I've seen this before)
'from eve's ruin' is the wordplay.
'from' indicates anagramming the letters (from the letters).
'eves'+'ruin'='evesruin'
'evesruin' anagrammed gives 'UNIVERSE'.
'things stemming' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for universe that I've seen before include "Everything that exists, everywhere" , "Sphere of thought" , "The totality of matter, energy and space" , "sphere of activity" , "mind-boggling concept" .)
