Respect man exploding bluff (10)
I believe the answer is:
escarpment
'bluff' is the definition.
(I've seen this before)
'respect man exploding' is the wordplay.
'exploding' indicates anagramming the letters.
'respect'+'man'='respectman'
'respectman' anagrammed gives 'ESCARPMENT'.
(Other definitions for escarpment that I've seen before include "Bluff" , "Steep slope - map's centre (anag)" , "Precipitous side of hill" , "Steep slope at edge of plateau" , "Face" .)
