Here are some additional details:
* Lao is spoken by the majority of the population and is used in government, education, and media.
* Lao is closely related to Thai, and many speakers of both languages can understand each other to some degree.
* French is also spoken by a significant portion of the population, particularly in urban areas, due to Laos' colonial history.
* English is increasingly being spoken, particularly in tourism and business, but it is still considered a foreign language.
* Other languages spoken in Laos include Hmong, Khmu, and Vietnamese, among others, depending on the region.
Therefore, while the official language is Lao, there are many other languages spoken in Laos, reflecting the country's diverse ethnic and cultural makeup.
