Think of a tube being like a fire hydrant, (triode) and the valve on top is the grid, the valve can be opened anywhere from 0 to 100%, allowing a constant flow of water out of it depending on how far it's open, now ad a variable, like a sine wave that will try to adjust (modulate) at valve by 20% (how fast does matter), but if it's too far open, it will hit the upper limit before you adjust it BY that 20% , and it will clip off the top, same if it's too far closed, a functional medium has to be set so you do not hit upper/lower limits of what you are trying to put through it, and thus get amplified.
I know this is a crude description, :p I'm trying to remember how my electronics teacher told it many many years ago.
