he official language is Spanish. The most characteristic of it is the use of “vos” instead of “you” in an informal way, and the use of “che” to speak to another person.
“Che” is a sign of confidence. It is not only used to draw the attention of the speaker but it also lets you call somebody without saying their names, for example: <“che”, can you tell me the time?>
The two languages which are most spoken by the tourist guides are English and Portuguese.
