Okay kiddo, let me explain! "-abad" is a word that is often used at the end of city names in some countries like India, Afghanistan, and Iran. It means "city" or "town" in those places. So, when you see a city name with "-abad" at the end, it means that it is a city or town in those countries. For example, Hyderabad in India, Kandahar in Afghanistan, and Tehran in Iran all have "-abad" at the end of their names. It's just like how in English we might have "-ville" or "-town" at the end of some city names, like Nashville or Germantown.
