Conclusion of Ibsen drama (3)
I believe the answer is:
end
'conclusion' is the definition.
(something's conclusion is its end)
'of ibsen drama' is the wordplay.
'of' says the answer is hidden in the clue.
'END' is hidden in the letters of 'ibsen drama'.
(Other definitions for end that I've seen before include "Purpose, objective" , "Culmination" , "Cesation, conclusion" , "Final stage" , "Cessation, conclusion" .)
