The word 'fulcrum' is used to talk about a point on which a lever rests and rotates. It's a support point that helps to lift or move something heavy. For example, when you're using a seesaw, the pivot in the middle is the fulcrum. You can also use the word 'fulcrum' to talk about a point of balance or support in general, not just with levers. So, if you're trying to explain how something balances or moves, you might use the word 'fulcrum' to describe the key point of support.
