What is the term for something that obstructs or separates, often by emphasizing differences?

The term "barriers" effectively captures the concept of something that obstructs or separates by emphasizing differences. Barriers can take many forms, including physical, social, or emotional obstacles, and they often highlight divisions within a population or between groups. The essence of barriers lies in their role of creating distinct separations that can lead to isolation or differentiation.

In a broader context, barriers can refer to systemic issues that prevent interaction, understanding, or collaboration between groups, thereby underscoring the importance of recognizing and addressing these divisions in various areas such as business, culture, or policy. This understanding is crucial in the field of business management, as acknowledging barriers can guide strategies for inclusion and communication.
