'count' is the definition.
(synonyms)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for matter that I've seen before include "Substance; be important" , "It occupies space, unlike mind or spirit" , "Carry weight" , "Physical substance" , "Affair; be important" .)
