Flinch while regarding contraceptive device (6)
I believe the answer is:
recoil
'flinch while' is the definition.
'recoil' can be an answer for 'flinch' (synonyms). I am unsure of the 'while' bit.
'regarding contraceptive device' is the wordplay.
'regarding' becomes 're' ('re' means regarding or about).
'contraceptive device' becomes 'coil' (coil is a kind of contraceptive device).
're'+'coil'='RECOIL'
Can you help me to learn more?
(Other definitions for recoil that I've seen before include "Move or spring back suddenly, perhaps in disgust" , "Fossil reptile" , "Jump back" , "Quail is here!" , "Flich or kick back" .)
