The different varieties of the Spanish language spoken in the Americas are distinct from each other as well as from those varieties spoken in the Iberian peninsula, collectively known as Peninsular Spanish and Spanish spoken elsewhere, such as in Africa and Asia. There is great diversity among the various Latin American vernaculars, and there are no traits shared by all of them which are not also in existence in one or more of the variants of Spanish used in Spain. A Latin American "standard" does, however, vary from the Castilian "standard" register used in television and notably the dubbing industry. Of the more than 498 million people who speak Spanish as their native language, more than 455 million are in Latin America, the United States and Canada in 2022. The total amount of native and non-native speakers of Spanish as of October 2022 exceeds 595 million.
Some of the regional varieties of the Spanish language are quite divergent from one another, especially in pronunciation and vocabulary, and less so in grammar.
In Spanish grammar, voseo is the use of vos as a second-person singular pronoun, along with its associated verbal forms, in certain regions where the language is spoken. In those regions it replaces tuteo, i.e. the use of the pronoun tú and its verbal forms. Voseo can also be found in the context of using verb conjugations for vos with tú as the subject pronoun.
Rioplatense Spanish, also known as Rioplatense Castilian, or River Plate Spanish, is a variety of Spanish originating in and around the Río de la Plata Basin, and now spoken throughout most of Argentina and Uruguay. It is the most prominent dialect to employ voseo in both speech and writing. Many features of Rioplatense are also shared with the varieties spoken in south and eastern Bolivia, and Paraguay. This dialect is influenced by Italian languages, due to the historically significant Italian immigration in the area, and therefore has several Italian loanwords and is often spoken with an intonation resembling that of the Neapolitan language of Southern Italy.
Jopara or Yopará is a colloquial form of Guarani spoken in Paraguay which uses a number of Spanish loan words. Its name is from the Guarani word for "mixture".

The term is of more geographical than linguistic relevance, since the dialects spoken in the various regions of Colombia are quite diverse. The speech of the northern coastal area tends to exhibit phonological innovations typical of Caribbean Spanish, while highland varieties have been historically more conservative. The Caro and Cuervo Institute in Bogotá is the main institution in Colombia to promote the scholarly study of the language and literature of both Colombia and the rest of Spanish America.

This influence is especially strong in rural areas.
