Why “seism” is a great word
SEISM — [Noun] A shaking of the Earth's surface; an earthquake or tremor. From Ancient Greek σεισμός (seismós, "shaking; earthquake"), from seíein ("to shake, quake"). Unlike "tremor," which implies a minor, incidental shudder, or the clinical "seismic event," a broader modern envelope for any vibration, "seism" is the primal, root noun for the phenomenon itself. It is the deep, tectonic groan, the silent lurch that spills a glass of water, and the profound, unsettling quiet that floods a city the moment the roaring stops. In that instant, the ground remembers it is not solid, and we are reminded we are only visiting.
