Indian title of respect (5)
I believe the answer is:
sahib
'indian title of respect' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for sahib that I've seen before include "European in India" , "Polite form of Indian address to a man" , "Indian gentleman" , "Respectful form of address to Indian man" , "Respectful term of address to an Indian man" .)
