A more thorough explanation:

Definition: Quamdiu (kwam-dee-yoo) is a Latin word that means "as long as" or "so long as." It was commonly used in legal documents to set a limit or condition.

1. The lease agreement stated that the tenant could stay in the apartment quamdiu they paid their rent on time.

2. The contract allowed the company to use the trademark quamdiu they continued to meet certain performance standards.

These examples show how quamdiu was used to set a condition or limit on an agreement. In the first example, the tenant was allowed to stay in the apartment as long as they paid their rent on time. In the second example, the company was allowed to use the trademark as long as they met certain performance standards.
