El Salvador is also home to two living indigenous languages. Kekchí, a Mayan language, has around 12,300 speakers. Pipil, also known as Nawat, is a language related to that of the Aztecs with around 11,100 speakers in El Salvador. A third indigenous language, Cacaopera, is extinct as of 2014. The Spanish spoken in El Salvador has some unique features, most prominently the use of the second-person pronoun "vos" instead of "tú" when speaking in informal situations.
