Why is Wednesday Spelled Like That?

Because Wednesday preserves an old spelling even though its pronunciation changed. It comes from Old English Wōdnesdæg, meaning “Woden’s day”—the day named after the Germanic god Woden (Odin). Over centuries: Wōdnesdæg → Wednesday → “Wenzday”. The spelling kept the historical d, but everyday pronunciation dropped that sound. English spelling often preserves these older forms even after pronunciation changes.
