A more thorough explanation:

Definition: Proscription is the act of forbidding something or the state of being forbidden. It can also refer to a specific restriction or prohibition.

Example 1: The proscription of smoking in public places has become more common in recent years.

Example 2: The proscription against using cell phones during class is strictly enforced in this school.

The examples illustrate how proscription involves the act of prohibiting or restricting certain actions or behaviors. In example 1, smoking in public places is prohibited, while in example 2, using cell phones during class is restricted. Both examples demonstrate how proscription can be used to maintain order and promote safety in various settings.
