Semblance, pretence (5)
I believe the answer is:
guise
I believe this is a double definition.
'semblance' is the first definition.
(I know that guise is a type of semblance)
'pretence' is the second definition.
(I know that pretence can be written as guise)
(Other definitions for guise that I've seen before include "Semblance; likeness" , "Show" , "Mask" , "Demeanour" , "General appearance" .)
