Saudade -

Saudade (European Portuguese: [sɐwˈðaðɨ], Brazilian Portuguese: [sawˈdadi] or [sawˈdadʒi], Galician: [sawˈðaðe]; plural saudades)[1] is a word in Portuguese and Galician that has no direct translation in English. It describes 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 may never return.[2] A stronger form of saudade may be felt towards people and things whose whereabouts are unknown, such as a lost lover, or a family member who has gone missing, moved away, separated, or died.
