wether
Pronunciation: /ˈwɛðə/

Origin:
Old English, of Germanic origin; related to Dutch weer and German Widder

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).
