Show leaver around (6)
I believe the answer is:
reveal
'show' is the definition.
('reveal' can be a synonym of 'show')
'leaver around' is the wordplay.
'around' indicates anagramming the letters.
'leaver' with letters rearranged gives 'REVEAL'.
(Other definitions for reveal that I've seen before include "Leaver (anag.)" , "Expose or disclose" , "Make public" , "Make known or visible" , "Expose, remove covering" .)
