What is the difference between Mumbai and bambai?

Mumbai and Bombay refer to the same city, which is currently called Mumbai. However, the name Bombay was more commonly used until 1995, when the city's name was officially changed to Mumbai.

The name "Bombay" is derived from the Portuguese words "Bom Bahia", which means "good bay". This name was given by Portuguese explorers in the 16th century. The name "Mumbai" is derived from the name of a local goddess, Mumbadevi.

The change of name from Bombay to Mumbai was motivated by several factors, including the desire to use an Indian name for the city, to reflect its history and culture, and to differentiate it from other cities with similar names.
