Searching for final determination (7)
I believe the answer is:
inquest
This clue might be a double definition.
'searching for' is the first definition.
The definition suggests a singular noun which matches the answer.
'final determination' is the second definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see an association between them that I don't see?
Can you help me to learn more?
(Other definitions for inquest that I've seen before include "Post-death enquiry" , "Inquiry into causes of an unexpected event" , "Post-mortem investigation" , "Coroner's investigation" , "hearing" .)
