What is the meaning of dictatorship in hindi?

Right then. The most common and direct word for 'dictatorship' in Hindi is तानाशाही (Taanashahi). You'll hear this used in everyday conversation and news reports. It perfectly captures the sense of tyranny and a ruler with absolute, unchecked power.

There's also a more formal, political term: अधिनायकवाद (Adhinayakvaad). Think of this as being closer to 'authoritarianism'.

Essentially, Taanashahi is the go-to word for what you're asking. It refers to a system of government where a single person or a small group holds all the power, without any constitutional limitations. Hope that helps.
