Not to be confused with "weather" and "whether," wether is a ram or billy goat that was castrated at a young age.Wethers can be housed with the female sheep or goats, but intact bucks and rams usually are kept separately.Wether, weather and whether are homophones. They sound the same, but have different spellings and meanings. Weather refers to climate conditions, as in rainy weather. Whether is a conditional conjunction that indicates a choice. You can decide whether to go to the movies. So be careful. If you say "We're having great wethertonight," it might sound like you are serving castrated goat for dinner.
Hope this helps:)
