Coupling and reusability are related in that a well coupled system is often a result of good reusability. When components in a system are loosely coupled, it means that they have fewer dependencies on one another and can be used more frequently without being modified for other applications. This makes the code easier to read, maintain, and reuse in other projects. On the other hand, when components in a system tightly couple with each other, they become less reusable because their functionality is dependent on their interrelatedness.
Cohesion and reusability go hand-in-hand as well. Cohesion refers to how closely related elements within a single component or module communicate with each other, while reusability is the ability of these elements to be used again for different purposes or contexts. A highly cohesive system typically has better reusability because all its parts are interconnected and working together towards achieving specific goals or tasks; thus making it easier to repurpose them for different applications than if they were unconnected entities scattered throughout the codebase.

Reusable modules should also exhibit high cohesion so that all its parts interact effectively within the same context; this enables clear communication between them which leads to better maintenance and debugging capabilities as well as increased readability for developers who may not be familiar with all aspects of an application’s design but need to modify or add features rapidly when needed. Low cohesion modules tend to contain disparate pieces of code which makes them difficult to use outside their original purpose even though individual elements might individually be highly reusable due to their lack of tight coupling from one another; ultimately lowering their overall effectiveness at providing solutions within multiple contexts simultaneously.
