Nostalgia is a fond glance back; saudade is heavier and more loving — it carries real ache and even loss while still holding warmth. Both miss the past; saudade holds on harder, and would rather not be cured of it.

What each one means
Saudade
Saudade is a Portuguese word for the bittersweet ache of missing someone or something absent — a longing so warm it is almost a form of love. It is the everyday way to say you miss a person, even one who will be back next week, and at its deepest it is held for a place or a version of life that may never return.
Nostalgia is the warm, wistful longing for the past — a bittersweet fondness for earlier times, places, or people, usually remembered a little rosier than they really were.
