The Spanish dialect in El Salvador shares many similarities to that of its neighbors in the region, but it has its stark differences in pronunciation and usage.

El Salvador, like most of Central America, uses voseo Spanish as its written and spoken form, similar to that of Argentina.

Notable characteristics of Salvadoran phonology include the following: In El Salvador, as in the other Central American nations, vos is the dominant second person singular pronoun used by many speakers in familiar or informal contexts.

In El Salvador, and neighboring areas of Honduras and Guatemala, vos, or more rarely usted, may be added to the end of a sentence to reiterate the listener's participation.

[12] In El Salvador and Guatemala it is common to place an indefinite article before a possessive pronoun, as in una mi tacita de café lit.

Salvadoran Caliche is used across social classes, although professional individuals tend to avoid it because it is not considered "proper" Spanish.

Lipski further elaborates that such linguistic shortage indicates a possible generalization that in recent decades Salvadoran dialectology has failed to advance as rapidly as the comparative work in other Latin American nations.
