SEAMARK — [Noun] Any elevated object on land or navigational aid at sea serving as a guide to mariners. From sea ("body of salt water") + mark ("visible indicator"). Compare landmark. Unlike "landmark" (which roots itself to terra firma) or "buoy" (which bobs at the mercy of waves), a seamark is both steadfast and fluid—a lighthouse cleaving the dark, a radio tower blinking through fog, or the silhouette of a distant headland rising like a promise from the horizon. These are the quiet conspirators of safe passage, the fixed points in a shifting world that whisper: *here, this way home.*
