A more thorough explanation:

Definition: Ad infinitum is a Latin term that means "without limit." It refers to something that continues indefinitely or without an end.

For example, if someone says they will keep studying ad infinitum, it means they will keep studying without any limit or end. Similarly, a company can have a duration ad infinitum, which means it will exist indefinitely unless its articles of incorporation specify a shorter period.

The examples illustrate the definition by showing that ad infinitum refers to something that continues without any limit or end. It emphasizes the idea of infinity and suggests that there is no boundary or restriction to what is being described.
