Order of worth (5)
I believe the answer is:
merit
This could be a double definition.
'order' is the first 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?
'worth' is the second definition.
(I know that merit is a type of worth)
'of' acts as a link.
Can you help me to learn more?
(Other definitions for merit that I've seen before include "Deserve or warrant" , "The M in OM" , "Value" , "Quality deserving reward" , "Advantage" .)
