Prepares to be knighted (6)
I believe the answer is:
kneels
'prepares to be knighted' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for kneels that I've seen before include "Adopts customary position for prayer" , "Awaits blessing" , "Genuflects" , "Adopts normal posture for prayer" , "Shows deference" .)
