Word said with a salute (3)
I believe the answer is:
sir
'word said with a salute' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sir that I've seen before include "Polite form of address to a man" , "Form of address for a knight" , "Male title of respect" , "Honourable title" , "Title of Kt or Bart" .)
