Hackneyed, tired (5)
I believe the answer is:
stale
I believe this is a double definition.
'hackneyed' is the first definition.
(I've seen this before)
'tired' is the second definition.
(I've seen this in another clue)
(Other definitions for stale that I've seen before include "Not fresh, being least" , "Old; musty" , "Unfresh" , "Musty - out of date" , "past the sell-by date" .)
