Let Me Make A Note of That

"Que saudade!

The word saudade (sah-ooh-dah-jee) has no direct translation in English, and it's a major source of linguistic pride for Brazilians. Use Que saudade! (kee sah-ooh-dah-jee) when you miss something so desperately, you have a heartache over it. People say Que saudade! when they remember their best friend who's now living far away, or their childhood beach. Brazilians also often say simply Saudades! at the end of e-mails to tell you they're missing you terribly."
