Evidence of persistent smoke detector? (11)
I believe the answer is:
stethoscope
This could be a double definition.
'evidence of persistent smoke' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'detector?' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
Can you help me to learn more?
(Other definitions for stethoscope that I've seen before include "Medical instrument" , "Instrument used in listening" , "listening device" , "Doctor's instrument" .)
