Medic died, succumbing to implausible irony? (8)
I believe the answer is:
metallic
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for metallic that I've seen before include "Of the nature of tin, iron, copper etc" , "like 28 [SILVER]" , "Like iron, gold, etc" , "Relating to a lustrous elementary substance" , "Relating to shiny chemical element" .)
