The name of which of the following countries closely means ‘country of 40 tribes’?

The answer is Kyrgyzstan. Its name is traditionally derived from 'kyrk' (forty) and 'yz' (tribe or clan), so it is read as the land of forty tribes. This is the standard etymology cited for UPSC, though scholars have debated its precise origin.

• Kazakhstan: named after the Kazakhs, a word linked to a sense of wandering or free warriors, not to forty tribes.
• Tajikistan: means land of the Tajiks, a Persian-speaking people, so its roots do not give the forty-tribe meaning.
• Uzbekistan: means land of the Uzbeks, named after Khan Uzbek of the Golden Horde, roughly 'own master' or 'independent ruler'.

Core concept: the ethnonyms behind Central Asian state names, which reflect the Turkic and Persian layers of the region and the Soviet-era national delimitation of 1924-36. Mains angle: India's Central Asia engagement, including the Connect Central Asia policy, is built on these shared histories.

Trap: candidates pick Kazakhstan by default because it is the largest state in the region, or they mix up the ethnonyms with the country names. Link each name to its people to avoid this.
