Saudade

Saudade, a word that can only be perfectly expressed in portuguese and has such a beautiful meaning... saudade, you only feel if you really love. Everyone feels saudade, but only portuguese speakers can really tell it. The dictionary tries to explain it, but it is not able to translate:

"saudade (f)
n. missing, nostalgia; longing, yearning
Saudade (singular) or Saudades (plural) (pron. IPA [] in European Portuguese, [] in Galician, and [] or [] in Brazilian Portuguese) is a Portuguese and Galician word for a feeling of longing for something that one is fond of, which is gone, but might return in a distant future. It often carries a fatalist tone and a repressed knowledge that the object of longing might really never return."

It is that feeling that makes you feel your heart tight, makes you sigh. Can make you smile, can make you cry.
