The word "sink" traces back to Old English sincan, meaning "to become submerged in liquid." It shares Proto-Germanic roots with Dutch zinken and German sinken, all derived from the Proto-Indo-European sengʷ- ("to sink, drop"). Originally describing physical submersion, its meaning expanded metaphorically to include decline (e.g., "sinking spirits"). The noun form (basin) emerged in the 15th century, referencing its function as a place where water "sinks" away.
