Reveal pretence (4)
I believe the answer is:
show
I believe this is a double definition.
'reveal' is the first definition.
('show' can be a synonym of 'reveal')
'pretence' is the second definition.
(show is a kind of pretence)
(Other definitions for show that I've seen before include "Allow to be seen" , "Display or exhibition" , "Musical featuring 'Old Man River'" , "Entertainment - guide" , "Point out - parade" .)
