The Chinese word **留恋** (liúliàn) is a compound formed by combining two semantically related characters: **留**, meaning "to stay" or "to remain," and **恋**, meaning "to love," "to feel attached," or "to long for." Together, they create a single concept that describes the emotional state of being unwilling to leave a person, place, or time due to fondness and deep attachment, thus encapsulating the sense of nostalgic longing or reluctance to part. This formation follows a common pattern in Chinese where two verbs or stative verbs are joined to express a more complex and nuanced psychological or emotional state.
