Che (Spanish: [tʃe], Portuguese: tchê [ˈtʃe]; Valencian: xe [ˈtʃe]) is an interjection (i.e. a vocative expression) commonly used in Argentina, Uruguay, and in the Spanish autonomous community of Valencia. In the Southern Cone (especially in Rioplatense Spanish), it is a form of colloquial slang used in a vocative sense as "friend" and thus loosely corresponds to expressions such as "mate," "pal," "man," "bro," or "dude," as used by various English speakers. As a result, it may be used either before or after a phrase: "Man, this is some good beer," or "Let's go get a beer, bro." It can be added to an explicit vocative to call the attention, playing the role of "Hey," for instance: "Che, Pedro, ¡mirá!" or "Hey, Pedro, look!" Che is also utilized as a casual speech filler or punctuation to ascertain comprehension, continued interest, or agreement. Thus che can additionally function much like the English words "so," "right," or the common Canadian phrase "eh."
Che can also be found in some parts of Paraguay, Brazil ("tchê"), Peru, and Bolivia, as a result of their close vicinity to Argentina. In other Hispanic American countries, the term che can be used to refer to someone from Argentina. For example, the famous Argentine revolutionary Ernesto "Che" Guevara earned his nickname from his frequent use of the expression, which to his Cuban comrades in the Cuban Revolution was a curious feature of his idiolect. As a result, Guevara is popularly known simply as el Che (the Che) in many Latin American countries.
