I can name thousands of world cities because there are many cities globally, ranging from large metropolises to smaller urban areas. For perspective, there are lists available that rank thousands of cities by population or alphabetically, including major cities like Tokyo, Delhi, Shanghai, Dhaka, Mumbai, São Paulo, Mexico City, Cairo, London, Paris, and many more. People commonly can name at least 30 major cities around the world without difficulty, and some can name hundreds or even over a thousand cities if including smaller cities or towns. Online quizzes and lists show that naming over 200 cities is possible for some, especially when including global capitals, population centers, and regional cities across diverse countries. If you want, I could start listing some notable or large world cities, or if you have a specific continent or country in mind, I can name cities from there. Just let me know! For example, some of the largest cities by population include Tokyo, Delhi, Shanghai, Dhaka, São Paulo, Mexico City, Cairo, Mumbai, Beijing, Osaka, New York City, etc.
