What will you have if you name yours? (6)
I believe the answer is:
poison
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Other definitions for poison that I've seen before include "Meat for someone else" , "Venom, toxin" , "Eg, strychnine" , "Eg, toxin" , "If taken, it can harm or kill" .)
