Result of poor cleaning is germs in surgery (9)
I believe the answer is:
griminess
'result' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'poor cleaning is germs in surgery' is the wordplay.
'is germs in' anagrams to 'GRIMINESS'.
However, I am not sure how the anagram is indicated.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for griminess that I've seen before include "Amount of muck" , "Quality of coal" .)
