🎯 How This Word Works in UPSC Writing

The condition of a society holding together, sustained by shared institutions, trust and a sense of common belonging. It is the outcome the Preamble's fraternity clause aims at, and the point that lifts a GS1 answer is that cohesion does not require uniformity: a diverse society can be highly cohesive if its institutions are seen as fair by all groups. Perceived fairness, not sameness, is what does the work.

⚖️ Don’t Confuse It With
