What's Tag

As you may know, questions are organized under broad categories. Each category can include various types of questions. For example, the "History" category might contain questions about the Revolt of 1857, Shivaji Maharaj, Ancient History, Buddhism, and more.

To further refine this organization, we've introduced tags, which act as sub-categories to group questions more specifically.

Verified users can add tags to any question. If you have any suggestions regarding this system, we'd love to hear from you. Contact Us
