Sense: noun/1
All four words describe a ruler, but they differ in region, scale, and cultural tradition. An emperor rules a large empire, often composed of multiple nations — the Mongol emperors were called khans, so the two titles overlapped in that context. A king typically rules a single nation or kingdom and is used mainly in European and some Asian monarchies. A sultan is the Islamic title for a monarch, common in the Ottoman Empire, the Middle East, and parts of South Asia such as the Sultanate of Oman. A chieftain governs a single tribe or clan, usually on a smaller scale. A khan could be a chieftain of one tribe or the emperor of millions, depending on the era. In practice, the Mongol ruler Genghis Khan is called a khan in English, while the Ottoman ruler Suleiman is called a sultan, and the British ruler is called a king — the title reflects the culture and region as much as the rank.

Etymology
The word 'khan' comes from the Old Turkic word 'qan' (chief, ruler), which was adopted by the Mongols during their rise to power in the 12th–13th centuries. Through Persian 'khān' it spread into Arabic, Russian, and eventually European languages following the Mongol invasions. The title is most famously associated with Genghis Khan (c. 1162–1227) and his grandson Kublai Khan, who ruled the Mongol Empire at its height. The second sense (roadside inn) developed from the same root in Persian and Turkish, where a 'khan' was a place where a ruler provided shelter for travellers — a practical extension of the ruler's role as a protector.
