Make no move to anaesthetise (6)
I believe the answer is:
freeze
'anaesthetise' is the definition.
(freezing is a kind of anaesthetizing)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for freeze that I've seen before include "shivering" , "Change to ice" , "Stand motionless" , "Harden into ice" , "Peg" .)
