Hospital department not looking so good? Measure of disorder here (7)
I believe the answer is:
entropy
'disorder here' is the definition.
'entropy' can be an answer for 'disorder' (thesaurus). I am unsure of the 'here' bit.
'hospital department not looking so good? measure' is the wordplay.
'hospital department' becomes 'ENT' (abbreviation for Ear, Nose and Throat department).
'not looking so good? measure' becomes 'ropy' (I can't justify this - if you can you should believe this answer much more).
'ent'+'ropy'='ENTROPY'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for entropy that I've seen before include "Thermodynamic quantity" , "Measure of the disorder of a system" , "Try open (anag) - disorder in the system" , "state of increasing disorder" , "lack of order" .)
