## TL;DR

Converts interface of a class into another interface clients expect. Lets incompatible interfaces work together. Object adapter (composition) preferred over class adapter (inheritance).

## Core Explanation

Example: wrapping a third-party logging library behind your application's Logger interface, enabling easy replacement. Adapter vs. Facade: Adapter changes interface; Facade simplifies a complex subsystem with a new unified interface. Bridge pattern separates abstraction from implementation.
