Jewish salutation (6)
I believe the answer is:
shalom
'jewish salutation' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for shalom that I've seen before include "Hebrew greeting meaning peace" , "Hebrew "ciao"" , "Jewish word of greeting or leave-taking" , "Jewish expression of greeting or farewell" , "Traditional Jewish greeting meaning peace" .)
