A poison (7)

Ross

I believe the answer is:

cyanide

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">a poison</span>' is the definition.<br/ ><span class="explanation-format__explanation">(cyanide is poisonous)</span><br/ ><br/ >This is the entire clue.<br/ ></span>

(Other definitions for cyanide that I've seen before include "Nice day (anag) - poison" , "Highly toxic substance" , "Poisonous compound" , "killer" , "Extremely poisonous salt" .)

I've seen this clue in the Sydney Morning Herald and The Telegraph.
