Cliff's affable deception (5)
I believe the answer is:
bluff
I believe this is a triple definition!
'cliff's' is the first definition.
(thesaurus)
'affable' is the second definition.
(thesaurus)
'deception' is the third definition.
(bluff is a kind of deception)
(Other definitions for bluff that I've seen before include "Attempt to deceive" , "Pretend - headland" , "Steep bank; pretend confidence" , "Honest" , "Mislead; cliff; hearty" .)
