Partial apology struck revolutionary as show of respect (6)
I believe the answer is:
curtsy
'show of respect' is the definition.
'partial apology struck revolutionary' is the wordplay.
'partial' says the answer is hidden in the clue.
'revolutionary' says the letters should be written in reverse (letters revolve around).
'ystruc' can be found hidden inside 'apology struck'.
'ystruc' backwards is 'CURTSY'.
'as' acts as a link.
(Other definitions for curtsy that I've seen before include "Bend the knee in respect" , "Bend the knees in a gesture of respect" , "Female obeisance bending the knees" , "Woman's formal greeting" , "Kind of respectful bob made by women" .)
