A lovely word

Saudade

a Portuguese and Galician word which describes a deep emotional state of nostalgic longing for something, somewhere or someone that one was fond of and which is lost. It often carries a repressed knowledge that the object of longing might really never return.

Saudade has been described as a "vague and constant desire for something that does not and probably cannot exist ... a turning towards the past or towards the future".

Saudade was once described as "the love that remains" or "the love that stays" after someone is gone. Saudade is the recollection of feelings, experiences, places or events that once brought excitement, pleasure, well-being, which now triggers the senses and makes one live again.
