 6. **Memento pattern**: Provides the ability to restore an object to its previous state (rollback).
 7. **Null Object pattern**: Designed to act as a default value of an object.
 8. **Observer pattern**: a.k.a. P**ublish/Subscribe** or **Event Listener**. Objects register to observe an event that may be raised by another object.
-9. **Weak reference pattern**: De-couple an observer from an observable.
+9. **Weak reference pattern**: De-couple an observer from an observable event.
 10. **Protocol stack**: Communications are handled by multiple layers, which form an encapsulation hierarchy.
 11. **Scheduled-task pattern**: A task is scheduled to be performed at a particular interval or clock time (used in real-time computing).
 12. **Single-serving visitor pattern**: Optimize the implementation of a visitor that is allocated, used only once, and then deleted.
 13. **Specification pattern**: Recombinable business logic in a boolean fashion.
 14. **State pattern**: A clean way for an object to partially change its type at runtime.
 15. **Strategy pattern**: Algorithms can be selected on the fly.
