🕰️💭 nostalgia = Greek nostos (homecoming) + algos (pain): ache to go home
Spanish nostalgia comes from Greek nostos, meaning return home, plus algos, meaning pain. Literally it is homesickness, the ache for a place or time you cannot return to. Same spelling as English, so the link is easy to keep.
