Step 1: What deliberation and negotiation mean here.
Deliberation is weighing a matter through discussion before deciding, and negotiation is settling differences through give and take rather than force.
Step 2: Where this happens in practice.
Bills are debated clause by clause in Parliament and state assemblies, with members from different parties raising objections and suggestions before a law is finally passed.
Step 3: Why this matters for a diverse society.
A country with many religions, languages and regions cannot please everyone with a single decision, so talking things through and adjusting positions is what lets minority voices be heard and keeps decisions widely acceptable.
Step 4: Conclusion.
Because it relies on debate, consultation and compromise rather than one sided orders, democracy is correctly described as a system built on deliberation and negotiation.
