Blunt, candid (5)
I believe the answer is:
frank
I believe this is a double definition.
'blunt' is the first definition.
(I know that blunt can be written as frank)
'candid' is the second definition.
(I know that candid can be written as frank)
(Other definitions for frank that I've seen before include "Outspoken" , "Blunt; honest" , "Without evasion" , "Open" , "Old German" .)
