knowledge as true belief

Knowledge as true belief means that for you to truly "know" something, you must believe it is true, and it actually must be true in reality. Simply believing something isn't enough; it has to correspond with facts or reality. For example, if you believe it is raining outside and it indeed is, then you have a true belief. When this belief is accurate and supported by evidence, it becomes what we call knowledge. So, knowledge combines your genuine belief with the truth of that belief in the real world.
