Wit appears in Ibsen sequence (5)
I believe the answer is:
sense
'wit' is the definition.
(thesaurus)
'in ibsen sequence' is the wordplay.
'in' indicates a hidden word.
'SENSE' is hidden in the letters of 'ibsen sequence'.
'appears' acts as a link.
(Other definitions for sense that I've seen before include "may be common" , "Feel intuitively" , "See 16" , "Eg, taste or touch" , "Feeling - reason" .)
