Here are some examples:
* "I merely wanted to ask a question." (Meaning: I had no other intention besides asking a question.)
* "The problem is merely a misunderstanding." (Meaning: The problem is not serious or complex, it's just a misunderstanding.)
* "He's merely a student." (Meaning: He is only a student, he's not a teacher or a professional.)
"Merely" can sometimes make a statement sound less important or significant. It can also be used to express a contrast or a limitation.
