Tease is acceptable in show (7)
I believe the answer is:
provoke
'tease' is the definition.
(thesaurus)
'acceptable in show' is the wordplay.
'acceptable' becomes 'ok'.
'in' means one lot of letters goes inside another.
'show' becomes 'prove' (proving is a kind of showing).
'ok' going inside 'prove' is 'PROVOKE'.
'is' acts as a link.
(Other definitions for provoke that I've seen before include "Deliberately annoy" , "Incense" , "needle" , "Incite to anger" , "Affront" .)
