"Witness” people (5)
I believe the answer is:
amish
'witness people' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for amish that I've seen before include "One 24 [IN-SECT]" , "Community that settled in America" , "Relating to a strict US Mennonite sect" , "strict Pennsylvanian?" , "Mennonite sect members" .)
