Though actually the word began as a doctor's name for homesickness. In 1688 Johannes Hofer built it in New Latin from Greek nostos, 'returning home', and algos, 'pain', to match German Heimweh, 'home-pain'. At first it was missing home so much it hurt. Later, helped along by French writing, it opened out to missing any past that feels sweeter than now.
