Silver implanted in audio device? Cool (5)
I believe the answer is:
magic
'cool' is the definition.
Both the answer and definition are adjectives. Maybe you can see a link between them that I don't see?
'silver implanted in audio device?' is the wordplay.
I cannot quite see how this works, but
'silver' could be 'ag' (Ag is the chemical symbol for silver) and 'ag' is found within the answer.
'audio device?' could be 'mic' (microphone) and 'mic' is found in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for magic that I've seen before include "Great" , "Witchcraft" , "Necromancy" , "Enchanting quality" , "Entertainment at a children's party?" .)
