Make oneself fearfully small (6)
I believe the answer is:
cringe
'make' is the definition.
The definition and answer can be both to do with motion as well as being verbs in their base form.
Perhaps you can see an association between them that I don't see?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for cringe that I've seen before include "Crouch" , "Start" , "Cower in embarrassment or fear" , "Shrink away in fear" , "Recoil in embarrassment" .)
