Death of ethics over time (9)
I believe the answer is:
mortality
'time' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'death of ethics over' is the wordplay.
'death of' becomes 't' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ethics' becomes 'morality' (synonyms).
'over' means one lot of letters goes inside another.
't' placed within 'morality' is 'MORTALITY'.
Can you help me to learn more?
(Other definitions for mortality that I've seen before include "State of humanity" , "Death" .)
