American rapper trapped by defective mine machine (6)
I believe the answer is:
eminem
'american rapper' is the definition.
I know nothing about this answer so I can't tell whether this works.
'trapped by defective mine machine' is the wordplay.
'trapped by' says the answer is hidden in the clue.
'EMINEM' is hidden in the letters of 'defective mine machine'.
Can you help me to learn more?
(Other definitions for eminem that I've seen before include "US rapper" , "Rap artist" .)
