Completely disorganised having broken limb - chaos! (9)
I believe the answer is:
shambolic
'completely disorganised' is the definition.
'shambolic' can be an answer for 'disorganised' (I've seen this before). I'm not sure about the 'completely' bit.
'broken limb chaos' is the wordplay.
'broken' is an anagram indicator.
'limb'+'chaos'='limbchaos'
'limbchaos' is an anagram of 'SHAMBOLIC'.
'having' acts as a link.
Can you help me to learn more?
(Other definitions for shambolic that I've seen before include "all over the place?" , "Informally chaotic and disorganised" , "Chaotic, mismanaged" , "In a total mess" , "Chaotic and inefficient" .)
