A more thorough explanation:

Definition: Regrating is the act of buying goods, especially necessary provisions, from a market with the intention of reselling them in or near the same market at a higher price. It is also the resale of such goods.

In England, regrating was considered a criminal offense.

Example: A farmer buys a large quantity of potatoes from a market and then sells them at a higher price in the same market or nearby. This is an example of regrating.

Explanation: The farmer is buying the potatoes with the intention of reselling them at a higher price, which is the act of regrating. This practice was considered illegal in England because it caused the prices of goods to increase, making it difficult for people to afford necessary provisions.
