A more thorough explanation:

Definition: Ad terminum annorum is a Latin legal term that means "for a term of years."

Example: A lease agreement that states a tenant can rent a property for five years is an example of ad terminum annorum.

Explanation: Ad terminum annorum is commonly used in legal documents, such as lease agreements, to specify the duration of a contract or agreement. In the example given, the lease agreement specifies that the tenant can rent the property for a term of five years, after which the agreement will expire. This term is important because it sets a clear timeline for the agreement and helps both parties understand their obligations and responsibilities during that time.
