Trivial; overused
I believe the answer is:
trite
This clue is a double definition.
'trivial' is the first definition.
(thesaurus)
'overused' is the second definition.
(I've seen this in another clue)
(Other definitions for trite that I've seen before include "Overfamiliar through overuse" , "(Of an idea) lacking in originality" , "all vigour is gone" , "Stock" , "used till novelty's worn off" .)
