It may be called rough and hearty (5)
I believe the answer is:
bluff
I believe this is a triple definition!
'it may be called' is the first definition.
(I've seen this in another clue)
'rough' is the second definition.
(thesaurus)
'and' acts as a link.
'hearty' is the third definition.

(Other definitions for bluff that I've seen before include "Mislead; cliff; hearty" , "Deceive by concealing weakness" , "Rocky outcrop" , "Challengers may call it" , "Act deceptively; steep cliff" .)
