Marchitada means "withered" or "faded." It's a descriptive and evocative word that paints a vivid picture of something losing its vitality.
In this song, Emmanuel uses it metaphorically to describe his heart: "Si ves una flor marchitada en el suelo, es mi corazón" (If you see a withered flower on the ground, it's my heart). This powerful imagery conveys deep sadness and vulnerability, making it a memorable and emotionally resonant word.
