Silly, pointless (7)
I believe the answer is:
fatuous
This clue is a double definition.
'silly' is the first definition.
(I've seen this before)
'pointless' is the second definition.
(I've seen this before)
(Other definitions for fatuous that I've seen before include "Foolish or silly" , "Absurd" , "Witless" , "Absurdly stupid" , "Foolish, senseless." .)
