Nostalgia

A bittersweet longing for the past — often for a personal or cultural moment now inaccessible. Originally coined as a medical diagnosis for homesick soldiers, the term has shed its clinical sense and now denotes the affective pull of memory itself: the way a smell, a song, or a scrap of childhood detail can collapse the distance between past and present. A central register in coming-of-age writing, where the careful reconstruction of small physical sensations — the chlorine tang at the pool, the queue for the high board — becomes the engine of feeling.
