Old English weder, of Germanic origin; related to Dutch weer and German Wetter, probably also to the noun wind1
Do not confuse weather with wether or whether. Weather means 'conditions in the atmosphere such as temperature, rain, etc.' (if the weather’s good we’ll go for a walk); a wether is a castrated male sheep; whether means 'if', or is used to show doubt or a choice (she wasn’t sure whether to be flattered or outraged).
