Origin

The character combines a heart radical at the bottom, which classifies this as a word about emotions and feelings, with the character 莫 on top that serves as a sound hint for pronunciation. The 莫 component doesn't contribute its own meaning here—it's mainly there to suggest how the character should be pronounced. Together, the parts create a character that expresses the emotional yearning or longing that happens in the heart when you deeply love or pine for someone.
