The official language of Bolivia is Spanish. Most businesses and school classes are conducted in Spanish. However, Spanish speakers in Bolivia usually speak at least one indigenous language as well. More than 55% of the population speak either Quechua or Aymara. 

Spanish is a fairly formal language. For instance, there are two ways of saying "you." When someone is talking to an older person or a stranger, they use the formal pronoun ústed instead of the more informal tú. In the highlands, Spanish is spoken slowly and precisely. In the lowlands, it is spoken more quickly, and sometimes the endings of words are not pronounced. 

Aymara was spoken in Bolivia before the land was conquered by the Incas. Quechua was the language of the Incas. Originally, these languages had no written form. Now both languages are written down and there are Aymara and Quechua newspapers. Several Aymara and Quechua words and expressions are used in Bolivian Spanish. These words include inti, which means "sun" in both Aymara and Quechua, and tata, which means "father" or "old man." Both Aymara and Quechua also include many Spanish words. The language spoken in the town of Cochabamba mixes Quechua and Spanish.

Bolivia's indigenous languages incorporate new ideas in creative ways. For instance, the Quechuan word for airplane, latapisco, literally means "metal bird."
In the Amazon region, the indigenous languages include Chiquitano, Guaraní, Chiriguano, Guayrayu and Tsimané. Some of these languages are spoken by fewer than one hundred people and are in danger of becoming extinct. A great deal of knowledge and a unique way of seeing the world are lost each time a language becomes extinct.

 Bolivians value hospitality and personal contact. They tend to have a relaxed view of time. When they are talking with someone, they feel it is important to finish the conversation, even if this makes them late for an appointment. Greetings are also important. When Bolivians come to a party, they will usually greet each guest individually. Women usually kiss on the cheek while clasping hands. Men usually shake hands. If the men are close friends, they may shake hands, embrace and then shake hands again.
