Low bow of respect (6)
I believe the answer is:
salaam
'low bow of respect' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for salaam that I've seen before include "Oriental greeting with bow of obeisance" , "Oriental greeting or homage" , "Muslim greeting gesture" , "Muslim form of salutation" , "Peaceful greeting" .)
