Flinch — fawn (6)
I believe the answer is:
cringe
I believe this is a double definition.
'flinch' is the first definition.
(I know that flinch can be written as cringe)
'fawn' is the second definition.
(I know that fawn can be written as cringe)
(Other definitions for cringe that I've seen before include "Recoil in embarrassment" , "Cower in embarrassment or fear" , "Start" , "Shrink in fear or horror" , "Shrink away in fear" .)
