Saudade

Saudade is a deep emotional state of nostalgic or profound melancholic longing for an absent something or someone that one loves. Moreover, it often carries a repressed knowledge that the object of longing might never return. One English translation of the word is missingness, although it might not convey the feeling of deep emotion attached to the word “saudade”. Stronger forms of saudade might be felt towards people and things whose whereabouts are unknown, such as a lost lover, or a someone who has gone missing, moved away, separated, or died.

Saudade was once described as “the love that remains” after someone is gone.
