Disorder with Eden garment being abandoned? (11)
I believe the answer is:
derangement
'disorder' is the definition.
(I've seen this before)
'with eden garment being abandoned?' is the wordplay.
'with' means one lot of letters go next to another.
'being abandoned?' indicates an anagram (the original order is abandoned).
'eden' next to 'garment' is 'edengarment'.
'edengarment' anagrammed gives 'DERANGEMENT'.
(Other definitions for derangement that I've seen before include "Madness; disorder" , "Disorder; insanity" .)
