I'm up on something snappy, stylish electronic device (9)
I believe the answer is:
microchip
'device' is the definition.
(I know that microchip is a type of semiconductor)
'i'm up on something snappy stylish electronic' is the wordplay.
I cannot really understand how this works, but
'i'm' could be 'i' (I've seen this in other clues) and 'i' is found within the answer.
'stylish' could be 'hip' (I've seen this in another clue) and 'hip' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for microchip that I've seen before include "processor?" , "Integrated circuit" , "Tiny circuit bearer" , "Tiny proportion of potato" , "ID for pet" .)
