Maybe you have a count. Maybe you have a baron. And you could keep going down this chain of nobility where one noble is pledging fealty to the king, is a king's vassal, but then they are lord of another vassal. And you keep going all the way down until you get to a plot of land where the actual work might occur. And that term is often referred to as a manor. And a manor just doesn't happen at the bottom of this pyramid. A duke can have a manor, and they can split up the rest of their duchy and give sections of it to form counties that could be led by counts.
