A stiff examination (7)
I believe the answer is:
autopsy
This could be a double definition.
'a stiff' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'examination' is the second definition.
(I know that autopsy is a type of examination)
Can you help me to learn more?
(Other definitions for autopsy that I've seen before include "final critical analysis" , "An official post-mortem examination" , "Dissection of a body to determine the cause of death" , "Pays out (anag.)" , "final examination" .)
