Consider noble matter (5)
I believe the answer is:
count
I believe this is a triple definition!
'consider' is the first definition.
(synonyms)
'noble' is the second definition.
(count is a kind of noble)
'matter' is the third definition.
(Other definitions for count that I've seen before include "Tolstoy was one" , "Total" , "Titled man" , "Sum up" , "European title" .)
