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."[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. It may also be translated as a deep longing or
yearning for something that does not exist or is unattainable.
