"It's something of a mischievous question, but mischief is also important in learning, so I'll ask.  One common way to ask what something means, is to ask what you experience when that proposition is true.  If you say 'water is liquid', for example, and I ask you what that means, you might tell me that water is the clear stuff inside a glass, and that liquid means that it tries to cling to itself but has no set shape, and so conforms itself to the shape of its container; and when I see you pour the water from the glass, onto the floor, I should expect to see it spread out across the floor, while still locally clinging to itself and staying in contiguous puddles.  Now, what do you see when one equals one?"
