The lingua franca for India and Pakistan is Hindi/Urdu--which are functionally the same language.
The lingua franca of India is Hindi, which is spoken by the largest number of people in the country. However, English is also widely used as a second language for communication, especially in government, business, and education.
English is the predominant world lingua franca, as it is widely used in international business, diplomacy, science, and tourism. It is often spoken as a second language by people around the world.
The first lingua franca was likely Akkadian, an ancient Semitic language used in the Mesopotamian region around 2500 BCE for trade, diplomacy, and communication between different cultures. It later evolved into Aramaic which became a major lingua franca in the Near East.
English serves as the lingua franca in many international business settings.
A lingua franca is a common language that is used for communication between people of different languages and cultures. Lingua Franca is not a country, nor it is it located in any specific countries.
No Urdu is not a country. It is a language. It is the national language and lingua franca of Pakistan, and an official language of five Indian states and one of the 22 scheduled languages in the Constitution of India.
The current lingua franca is English, but that may be set to change in the next few years.
The Lingua Franca status is a descriptive term, and not a fixed status. Lingua Francas cannot be preserved. They change with the times.
Currently, Europe's lingua franca is English. However, not so long ago, the lingua franca of Eastern Europe was Russian (and sometimes German, depending on the proximity of a country to Germany as opposed to Russia).
