Show subservience, in a way (5)
I believe the answer is:
kneel
'show subservience in a way' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for kneel that I've seen before include "Show obeisance" , "Rest on hassock" , "Prepare to be knighted" , "Kowtow" , "Get down to be knighted" .)
