Sprayer's title? (6)
I believe the answer is:
mister
I believe this clue is a double definition.
'sprayer's' is the first definition.
(device used for spraying a mist of water)
'title?' is the second definition.
(Other definitions for mister that I've seen before include "Mr" , "that's what you'd call him" , "Set rim (anag.)" , "Form of address to a man, used without his name" , "Bloke" .)
