Whether vs. Weather
Although “whether” and “weather” are pronounced alike for many speakers, they have different grammatical roles and meanings. “Whether” introduces alternatives or uncertainty, while “weather” most commonly names atmospheric conditions.
“Whether” is a conjunction about alternatives or uncertainty; “weather” usually refers to atmospheric conditions and also has separate verb senses.
