Stale, hackneyed (5)
I believe the answer is:
trite
I believe this is a double definition.
'stale' is the first definition.
(I've seen this in another clue)
'hackneyed' is the second definition.
(I know that hackneyed can be written as trite)
(Other definitions for trite that I've seen before include "Lyre string" , "(Of an idea) lacking in originality" , "all vigour is gone" , "Banal, commonplace" , "Stock" .)
