In English
Here is another example. A potter goes to a pond, digs out clay from it, and brings it home. He dumps the clay in front of his house. There is a pit in the pond as a result of his digging out clay from it. There is a mound of clay in front of his house. When the clay is dug out, a pit is formed, and when the same clay is deposited in one place, a mound is formed. The clay of the pit is the same as the clay of the mound. You have dug a pit to make a mound.
