Answer:
4. cliche
Explanation:
A cliche is an idea, phrase, or expression that was original or fresh once but that has been used so many times that became commonplace, boring and no longer attractive or effective. Phrases like “Actions speak louder than words,” “You can't judge a book by its cover” and “What doesn't kill you makes you stronger” are good examples of cliches: They are great phrases but have become boring, ineffective from much use.
