Loss of cohesion is disastrously disorientating (14)
I believe the answer is:
disintegration
'loss of cohesion' is the definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'disastrously disorientating' is the wordplay.
'disastrously' indicates an anagram (I've seen this in other clues).
'disorientating' anagrammed gives 'DISINTEGRATION'.
'is' is the link.
Can you help me to learn more?
(Other definitions for disintegration that I've seen before include "Process of breaking up" , "Falling apart" .)
