Characters in Beau Geste emphasising respect (6)
I believe the answer is:
esteem
'respect' is the definition.
(I know that respect can be written as esteem)
'characters in beau geste emphasising' is the wordplay.
'characters in' indicates the answer is hidden within the clue.
'ESTEEM' is hidden in the letters of 'beau geste emphasising'.
(Other definitions for esteem that I've seen before include "Venerate" , "'Regard, respect (6)'" , "Hold in deference and respect" , "judge" , "Favourable regard" .)
