Result of being so untidy it's a sickness? (8)
I believe the answer is:
disorder
'a sickness?' is the definition.
(thesaurus)
'result of being so untidy it's' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is found in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is present in the answer.
'being' could be 'dr' (Dr is an example) and 'dr' is found in the leftover letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for disorder that I've seen before include "Muddle" , "Disturbance of normal working, as of mind or body" , "Confusion, mess" , "breach of the peace" , "Indiscipline" .)
