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