A more thorough explanation:

Definition: In Scots law, a roup is a public sale by auction.

Example 1: The estate agent organized a roup to sell the property to the highest bidder.

Example 2: The farmer held a roup to sell his livestock to other farmers in the area.

These examples illustrate how a roup is a public sale by auction. In both cases, the seller is looking to get the best price for their goods, and potential buyers bid against each other until the highest bid is reached. The roup is a common way of selling property, livestock, and other goods in Scotland.
