Hebrew greeting (6)
I believe the answer is:
shalom
'hebrew greeting' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for shalom that I've seen before include "Jewish greeting and blessing" , "Jewish expression of greeting or farewell" , "Jewish word of greeting or leave-taking" , "Hebrew greeting meaning peace" , "Peace (in the Middle East!)" .)
