Kardashian matriarch (4)
I believe the answer is:
kris
'kardashian matriarch' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for kris that I've seen before include "Malayan slashing knife" , "Indonesian dagger; sounds like fold" , "Its flag has a maple leaf" , "Malayan dagger" , "Malay knife" .)
