Belarus is called Belarus because the name is derived from the Old East Slavic word "бѣлъ" (bělŭ) meaning "white" and "русь" (rus') meaning "Rus". The combination of these two words gives the meaning "White Rus" or "White Russia". This name is believed to have originated from the white clothing worn by the early Slavic people who inhabited the region. The name "Belarus" was officially adopted in 1991 when the country gained independence from the Soviet Union. **

Belarus was previously known as Byelorussia, a name that originated from the Russian language meaning "White Russia." However, the country's leadership and citizens wanted to emphasize their distinct national identity and move away from the association with Russia. Therefore, in 1991, after gaining independence from the Soviet Union, the country officially changed its name to Belarus, which means "White Ruthenia" in the Belarusian language, reflecting its historical ties to the region of Ruthenia. This name change was part of a broader effort to assert Belarus's sovereignty and cultural heritage. **

Belarus and Russia have a close relationship and are both part of the Union State, which aims to integrate the two countries economically and politically. However, there are several factors that have prevented them from fully joining together. These include differences in political systems, concerns about sovereignty and national identity, and disagreements over economic and military integration. Additionally, there are also internal and external pressures that influence the relationship between the two countries. **

No, Belarus is not Chechnya. Belarus is a country located in Eastern Europe, while Chechnya is a region in the North Caucasus region of Russia. They have different histories, cultures, and political systems. Belarus gained independence from the Soviet Union in 1991, while Chechnya has a history of conflict with Russia and has a different ethnic composition. **

Both terms, Belarus and White Russia, refer to the same country located in Eastern Europe. The name Belarus is the official name of the country, derived from the term "White Russia" which historically referred to the region. However, the term "White Russia" is considered outdated and carries connotations of the country's past under Russian rule. Therefore, it is more appropriate to use the term Belarus when referring to the country in a modern context. **

The official language spoken in Belarus is Belarusian, which is a Slavic language closely related to Russian and Ukrainian. Russian is also widely spoken and used in official and business settings, especially in urban areas and among the older generation. Additionally, there are also small minority languages spoken in Belarus, such as Polish, Ukrainian, and Yiddish. **

One cannot say "Belarus" anymore because the country's official name has been changed to "Belarus" from "Byelorussia" in 1991. The term "Belarus" is now the internationally recognized name for the country, and using the outdated term "Byelorussia" can be seen as disrespectful or insensitive. It is important to use the correct and current name for countries out of respect for their sovereignty and identity. **

Belarus and Russia have a long history of close ties and cooperation, but there are several factors that have prevented them from fully uniting. One major issue is the question of sovereignty and national identity, as Belarus has expressed a desire to maintain its independence and autonomy. Additionally, there are economic concerns, as a full union could potentially lead to unequal benefits for both countries. Political differences and disagreements over issues such as military integration and foreign policy also play a role in preventing a complete union between Belarus and Russia. **
