The Korean particle "만" is used to indicate exclusivity or limitation. It translates to "only" in English, emphasizing that something is restricted to a specific subject or object. For example, in the sentence "나만 갔어요" (I only went), "만" highlights that only the speaker went, excluding others. In addition to its use in sentences, "만" can also be combined with other particles to create nuanced meanings. For instance, when used with the subject marker "이/가," it can specify that only the subject is being discussed. This makes "만" a versatile tool in the Korean language for expressing singularity or restriction.
