A more thorough explanation:

Definition: Accroach (uh-krohch) is a verb that means to take power or control without having the authority to do so. This is also known as usurping.

Example 1: The new manager accroached the responsibilities of the senior manager without permission.

Example 2: The landlord accroached the tenant's privacy by entering the apartment without notice.

These examples illustrate how someone can take control or power without having the proper authority to do so. In the first example, the new manager took on responsibilities that were not assigned to them, while in the second example, the landlord violated the tenant's rights by entering their apartment without permission. Both actions are considered accroachment because they involve taking control or power without proper authorization.
