Andean Spanish

Andean Spanish is a dialect of Spanish spoken in the central Andes, from southern Colombia, with influence as far south as northern Chile and Northwestern Argentina, passing through Ecuador, Peru, and Bolivia. While similar to other Spanish dialects, Andean Spanish shows influence from Quechua, Aymara, and other indigenous languages, due to prolonged and intense language contact. This influence is especially strong in rural areas.

Phonology

 * In Andean Spanish, the is never aspirated in the final position and so is pronounced, not , but it is sometimes pronounced apical, rather than laminal, a trait characteristic of Northern Spain. The apical sound is sometimes perceived as transitional between  and , and it is associated with a large number of northern Spanish settlers in Andean region.  In southern Bolivia and northern Chile, syllable-final /s/ is mostly aspirated.
 * As in all American dialects of Spanish, Andean Spanish has seseo ( is not distinguished from ). Thus, casa ("house") and caza ("hunt") are homophones. However, in Cusco Region and Cajamarca, many speakers realize as  in many words, particularly in once, doce, trece.   Seseo is common to all of America, the Canary Islands, and several areas in southern Spain.
 * Especially in the Ecuadorian variant, coda is often voiced to  before a vowel or before a voiced consonant (including sonorants), but the latter is also a feature of most other Spanish dialects. In the Peruvian variant, it is palatalized before.
 * In Bolivia, Ecuador, and southern Peru, and  do not merge (lack of yeísmo).  In northern Ecuador,  tends to be pronounced as a voiced postalveolar fricative. However,  yeísmo is on the rise among Ecuador's middle and upper classes.
 * Often the vowels and  or  and  are merged because of the influence of the trivocal system of Quechua and Aymara.
 * and are assibilated to  and, respectively. This is in decline among the middle and upper classes.
 * is velar rather than glottal.
 * is realised as bilabial, sometimes with an epenthetic following.
 * Emphasis is given to the consonants but the vowels are weakened, especially for unstressed syllables (like in Mexican Spanish, but not as marked).
 * The intonation patterns of some Andean accents, such as those of Cusco, have been influenced by those of Quechua. Even monolingual Spanish speakers can show Quechua influence in their intonation.

Syntax and morphology
Voseo is common in the Bolivian and Ecuadorian Andes, largely among rural and poorer speakers. It is nearly extinct in Peru. Some speakers tend towards pronominal voseo, using vos with the tú conjugations of verbs, whereas more indigenous speakers tend to use the vos conjugations.

Words like pues, pero and nomás are often used similarly to the modal suffixes of Quechua and Aymara. They can be stacked at the end of a clause: Dile nomás pues pero.

"Just go ahead and tell him." Andean Spanish also widely uses redundant "double possessives" as in: De María en su casa estoy yendo.

"I'm going to Maria's house." This also shows how en can indicate "motion towards" in the Andes. En may also be used "before a locative adverb, as in Vivo en acá 'I live here' or En allá sale agua 'Water is coming out there.'"

Due to Aymara and Quechua influence, Andean Spanish often uses the pluperfect tense or clause-final dice "he/she says" to indicate evidentiality. Evidential dice is more common in monolingual Peruvian Spanish.

In upper Ecuador, a dar + gerund construction is common, ie: Pedro me dio componiendo mi reloj.

"Pedro fixed my watch."

Vocabulary
Andean Spanish typically uses more loans from Aymara and Quechua than other Spanish varieties. In addition, some common words have different meanings. Pie, meaning "foot," can refer to the whole leg, due to Aymara influence. Siempre ("always") can mean "still."
