Middle Easterner, furious, escalating a disturbance (9)
I believe the answer is:
damascene
'middle easterner' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for damascene that I've seen before include "gold inlay" , "inlaid work" , "Middle Easterner" , "steely ornamentation" , "as conversion is described" .)
