Ross

I believe the answer is:

protocol

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">diplomatic etiquette</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>

(Other definitions for protocol that I've seen before include "Procedural rules" , "Code of correct conduct" , "Draft treaty" , "Correct procedure" , "Formal code" .)

I've seen this clue in the Newsday.
