Threadbare; tired (4)
I believe the answer is:
worn
I believe this clue is a double definition.
'threadbare' is the first definition.
(similar in meaning)
'tired' is the second definition.
(similar in meaning)
(Other definitions for worn that I've seen before include "Threadbare" , "Frayed" , "Damaged by long use" , "Hackneyed, trite" , "Second-hand" .)
