Absurd tavern has a point (5)
I believe the answer is:
inane
'absurd' is the definition.
(I've seen this before)
'tavern has a point' is the wordplay.
'tavern' becomes 'inn' (I've seen this before).
'has' is an insertion indicator.
'point' becomes 'E' (compass point).
'inn' going around 'a' is 'inan'.
'inan'+'e'='INANE'
(Other definitions for inane that I've seen before include "Vacuous, silly" , "Vapid, fatuous" , "Lacking sense, silly" , "Without meaning or point" , "Fatuous, vacuous" .)
