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 a hidden word.
'ESTEEM' is hidden in the letters of '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" .)
