Shrink wrapping of rare electrical part (6)
I believe the answer is:
recoil
'shrink' is the definition.
(I know that shrink can be written as recoil)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for recoil that I've seen before include "Flinch or start back (6)." , "Jerk back" , "Flinch, starts back" , "Cringe" , "Spring back in horror" .)
