Hay, Hay que, Haber

The verb Haber has a special case that is very useful in Spanish and deserves to be pointed out. The form "hay" functions like a verb that doesn't need to be conjugated: it means both "there is" and "there are". For example, "Hay tres manzanas" means "there are three apples". When you add the word "que" to the word "hay", you get an expression with a different meaning: "hay que" means "to have to" or "one must". It works a lot like "tener que". While there aren't a lot of great resources online for this one, it's because you'll pick it up pretty quickly. Check out these links.
