The word "眷恋" is formed by combining the character "眷", which itself is composed of "目" meaning eye and "卷" meaning to roll or scroll, implying a sense of looking back or caring, with the character "恋", composed of "亦" meaning also and "心" meaning heart, denoting deep emotional attachment. Together, these characters create a compound word meaning to feel nostalgic attachment or yearning affection for someone or something.
