 * **`Abstraction`**
   - defines the abstraction's interface
   - maintains a reference to an object of type `Implementor`
-* **RefmedAbstraction**: Extends the interface defined by *Abstraction*
+* **RefinedAbstraction**: Extends the interface defined by *Abstraction*
 * **`Implementor`**: defines the interface for implementation classes. This interface doesn't have to correspond exactly to Abstraction's interface; in fact the two interfaces can be quite different. Typically the Implementor interface provides only primitive operations, and Abstraction defines higher-level operations based on these primitives
-* **`Concretelmplementor`**: implements the Implementor interface and defines its concrete implementation
