The word "whet" traces back to Old English hwettan, meaning "to sharpen," derived from Proto-Germanic hwatjaną. It is related to Old Norse hvetja and German wetzen. The core idea of sharpening evolved metaphorically to include stimulating non-physical things like appetite or interest. The word has retained its dual meanings—literal (sharpening blades) and figurative (sharpening desires)—since its earliest usage.
