Exhibitions by editor open to view (7)
I believe the answer is:
exposed
'open to view' is the definition.
(thesaurus)
'exhibitions by editor' is the wordplay.
'exhibitions' becomes 'expos' ('expo' can be a synonym of 'exhibition').
'by' is a charade indicator (letters next to each other).
'editor' becomes 'ed'.
'expos'+'ed'='EXPOSED'
(Other definitions for exposed that I've seen before include "Deprived of protection" , "vulnerable" , "Laid bare" , "Brought to light" , "in the nude" .)
