Part of Beau Geste emphasising respect (6)
I believe the answer is:
esteem
'respect' is the definition.
(I know that respect can be written as esteem)
'part of beau geste emphasising' is the wordplay.
'part of' indicates the answer is hidden within the clue.
'ESTEEM' is hidden within 'beau geste emphasising'.
(Other definitions for esteem that I've seen before include "Think well of" , "Venerate" , "Set a high value on" , "High opinion, great respect" , "Favourable regard" .)
