language

It's amazing how some in some languages, one little word can mean so much.  

Like in Portuguese: saudade.

It is a word for a feeling of nostalgic longing for something or someone that one was fond of and which has been lost.  

It often carries a fatalistic tone and a repressed knowledge that the object of longing might never really return. 

 It was once described as "the love that remains"

 or "the love that stays" after someone is gone.
