All South American Countries in Spanish: Complete Guide, Names, and Capitals

South America comprises twelve sovereign nations and one overseas territory. In Spanish, these entities are Argentina, Bolivia, Brasil, Chile, Colombia, Ecuador, Guyana, Paraguay, Perú, Surinam, Uruguay, Venezuela, and Guayana Francesa. Nine of these twelve independent states designate Spanish as an official language, forming the linguistic core of South American Hispanic geography and international relations.

Complete Linguistic and Geographic Reference Table

Accurate translation between English and Spanish requires paying close attention to orthographic accents (tildes), letter shifts (such as "z" to "s"), and country-specific demonyms (gentilicios). In standard international Spanish, country names must adhere to the orthographic standards established by the Real Academia Española (RAE).

The following table provides the formal geopolitical designations, capitals, demonyms, and linguistic statuses for every territory across the South American continent:

Detailed Profiles of Spanish-Speaking South American Nations

Nine independent South American nations maintain Spanish as an official state language. While they share a common tongue, each territory possesses unique political geography, linguistic features, and constitutional frameworks.

Argentina

• Official Name: República Argentina
• Capital: Buenos Aires
• Key Linguistic Trait: Argentinian Spanish is recognized globally for voseo (using vos instead of tú for the second-person singular) and yeísmo rehilado, where the "ll" and "y" sounds are pronounced as a soft "sh" or "zh."

Bolivia

• Official Name: Estado Plurinacional de Bolivia
• Capitals: Sucre is the constitutional and judicial capital, while La Paz serves as the executive and legislative seat of government.
• Key Linguistic Trait: Bolivia's 2009 Constitution recognizes Spanish alongside 36 indigenous languages. Quechua, Aymara, and Guaraní are widely spoken, influencing the phonetic rhythm and vocabulary of Bolivian Andean Spanish.

Chile

• Official Name: República de Chile
• Capital: Santiago (officially Santiago de Chile)
• Key Linguistic Trait: Chilean Spanish features distinct lexical innovations, frequent aspiration or elision of the final "s" sound, and a unique system of verbal voseo utilized in informal communication.

Colombia

• Official Name: República de Colombia
• Capital: Bogotá
• Key Linguistic Trait: Colombia is renowned for its regional diversity, ranging from the conservative, clear consonant pronunciation of the Andean interior (Bogotá, Medellín) to the Caribbean dialects of the northern coast, which exhibit syllable-final consonant weakening.

Ecuador

• Official Name: República del Ecuador
• Capital: Quito
• Key Linguistic Trait: Named directly after the Equator line (el ecuador), Ecuadorian Spanish diverges between the coastal varieties (Guayaquil) and the highland Andean varieties (Quito), where lexical borrowings from Kichwa are integrated into daily speech.

Paraguay

• Official Name: República del Paraguay
• Capital: Asunción
• Key Linguistic Trait: Paraguay is exceptionally bilingual. Guaraní and Spanish enjoy equal constitutional status. Most citizens speak Jopara, an intricate colloquial blend that mixes Spanish and Guaraní syntactic and lexical elements.

Perú

• Official Name: República del Perú
• Capital: Lima
• Key Linguistic Trait: Peruvian Spanish must always be written with an acute accent on the "u" (Perú). The coastal dialect centered in Lima provided the administrative benchmark for the Viceroyalty of Peru, maintaining a relatively conservative vowel and consonant structure.

Uruguay

• Official Name: República Oriental del Uruguay
• Capital: Montevideo
• Key Linguistic Trait: Sharing the Rio de la Plata basin with Argentina, Uruguayan Spanish features voseo and similar intonation, though it preserves distinct intonation patterns and unique local idioms.

Venezuela

• Official Name: República Bolivariana de Venezuela
• Capital: Caracas
• Key Linguistic Trait: Venezuelan Spanish belongs predominantly to the Caribbean linguistic family, characterized by the aspiration of the letter "s" before consonants and rhythmic cadence shared with coastal Colombia, Puerto Rico, and Cuba.

Non-Spanish-Speaking South American Nations

Four South American political entities do not speak Spanish as an official language. However, in formal Spanish writing, their names and demonyms must still follow Spanish grammatical rules:

1. Brasil (Brazil): The largest country on the continent speaks Portuguese. In Spanish, it is spelled with an "s" (Brasil), never with a "z." Its demonym is brasileño or brasilero.
2. Guyana: Formerly known as British Guiana, this sovereign country speaks English. In Spanish, it retains the spelling Guyana, and its inhabitants are guyaneses.
3. Surinam (Suriname): The official language of this former Dutch colony is Dutch, alongside widely spoken Sranan Tongo. In Spanish, the final "e" is omitted, making the standard name Surinam, with the demonym surinamés.
4. Guayana Francesa (French Guiana): An overseas department and region of France, this territory uses French as its official language. The currency is the Euro, and in Spanish, it is referred to as Guayana Francesa.

Grammatical and Orthographic Rules for Country Names in Spanish

Mastering South American country names in Spanish requires adhering to several essential grammar rules concerning orthography, grammatical gender, and the use of definite articles.

1. Orthographic Accents (La Tilde)

Unlike English, Spanish mandates written accent marks to preserve phonetic stress rules:

• Perú: Requires a written accent mark over the "u" because it is an oxytone word (palabra aguda) ending in a vowel. Omitting the tilde (Peru) is an orthographic error in Spanish.
• Bogotá: The capital of Colombia requires an accent mark on the final "a."
• Asunción: The capital of Paraguay carries an accent mark on the "o" because it ends in an "n."

2. Spelling Brazilian and Guyanese Toponyms

English writers frequently carry native spellings into Spanish texts. When writing in Spanish:

• Replace the "z" in Brazil with an "s": Brasil.
• Keep the "y" in Guyana, but note that historical or administrative regions like la Guayana venezolana use the regional stem with "y" or "i" depending on local legal codification.

3. Usage of Definite Articles with Country Names

In older or formal literary Spanish, several country names were preceded by a definite article: el Perú, la Argentina, el Ecuador, el Brasil, or el Uruguay.

According to modern guidelines from the Real Academia Española:

The inclusion of the definite article before most country names is optional and increasingly omitted in modern administrative, academic, and journalistic prose.

However, certain exceptions apply:

• When a country name is modified by an adjective or relative clause, the article is mandatory: la Argentina del siglo XIX (19th-century Argentina) or el Brasil contemporáneo (contemporary Brazil).
• Some countries maintain the article more consistently in formal speech, especially el Perú and el Salvador, though writing Perú without the article is entirely correct and standard in global reporting.

4. Capitalization of Demonyms

A frequent error among native English speakers is capitalizing nationalities and demonyms. In Spanish, demonyms (gentilicios) are treated as common nouns or adjectives and are never capitalized unless they begin a sentence:

• Correct: Ella es colombiana y él es chileno.
• Incorrect: Ella es Colombiana y él es Chileno.

Regional Groupings and Geopolitical Alliances

South American countries coordinate through several intergovernmental organizations. Understanding these groupings is vital for geopolitical, business, and translation contexts:

• Comunidad Andina (CAN): A trade bloc comprising Bolivia, Colombia, Ecuador, and Peru. These nations share regulatory frameworks, transport integration policies, and cultural agreements.
• Mercosur (Mercado Común del Sur): A major regional trade bloc founded by Argentina, Brasil, Paraguay, and Uruguay. Bolivia achieved full membership status, while Venezuela's membership remains suspended.
• El Cono Sur (The Southern Cone): A geographic and cultural sub-region encompassing Argentina, Chile, and Uruguay, frequently expanded to include southern Brazil and Paraguay due to climate, historical immigration patterns, and economic indices.
• Alianza del Pacífico: A Latin American economic initiative composed of Chile, Colombia, Mexico, and Peru, emphasizing commercial integration along the Pacific Rim.

Common Mistakes When Translating South American Geography

To ensure high technical precision in bilingual documentation, avoid these common translation mistakes:

• Using "America" exclusively for the United States: In the Spanish-speaking world, América is viewed as a single continent containing North, Central, and South subdivisions. Referring to the United States simply as América can cause confusion or offense; use Estados Unidos instead.
• Confusing the two capitals of Bolivia: Writing that La Paz is the sole capital of Bolivia is politically and legally incorrect. Sucre is the constitutional and historical capital, while La Paz is the seat of the executive and legislative branches.
• Mislabeling the official language of Brazil: Portuguese is the sole official language of Brazil. While Spanish is taught in many Brazilian schools, Portuguese remains the language of government, education, and commerce.
• Misplacing the gender of Colombia and Venezuela: Both Colombia and Venezuela are grammatically feminine nouns (la Colombia moderna, la Venezuela actual).

Frequently Asked Questions

How many countries are in South America in Spanish?

There are twelve sovereign nations (doce países soberanos) and one overseas department in South America: Argentina, Bolivia, Brasil, Chile, Colombia, Ecuador, Guyana, Paraguay, Perú, Surinam, Uruguay, Venezuela, and the French territory of Guayana Francesa.

Nine of these twelve independent nations speak Spanish as their official national tongue, while the remaining states speak Portuguese, English, Dutch, or French.

What are the capitals of all South American countries in Spanish?

The capitals in Spanish are Buenos Aires (Argentina), Sucre and La Paz (Bolivia), Brasilia (Brasil), Santiago (Chile), Bogotá (Colombia), Quito (Ecuador), Georgetown (Guyana), Asunción (Paraguay), Lima (Perú), Paramaribo (Surinam), Montevideo (Uruguay), Caracas (Venezuela), and Cayena (Guayana Francesa).

Most capital city names remain identical between English and Spanish, with slight orthographic variations such as the accent mark on Bogotá or the spelling of Brasilia and Cayena.

Why does Bolivia have two capitals listed in Spanish geography?

Bolivia has two capitals due to the Federal War of 1899, which resulted in a power compromise between regional elites in Sucre and La Paz.

Sucre remains the constitutional and historical capital hosting the Supreme Tribunal of Justice, whereas La Paz functions as the administrative capital where the presidential palace (Plurinacional Palace) and the national legislature operate.

Do you capitalize country names and demonyms in Spanish?

Country names are proper nouns and must always be capitalized in Spanish, but demonyms (gentilicios) must be written in lowercase.

For example, write Argentina with a capital "A," but write argentino or argentina with a lowercase "a." Capitalizing demonyms is an anglicism that violates the spelling rules of the Real Academia Española.

Is Brazil spelled with an "s" or a "z" in Spanish?

Brazil is always spelled with an "s" as Brasil in Spanish, exactly as it is written in Portuguese.

Writing Brazil with a "z" is correct in English, but it is considered an orthographic misspelling in any formal Spanish text.

Strengthen Your Spanish Language Expertise

Navigating South American geography in Spanish requires strict adherence to accents, correct spelling, and an understanding of regional terminology. Whether you are translating academic texts, localizing global software, or drafting commercial contracts, using the correct toponyms and demonyms is essential for clear communication.
