Often when we ask our clients what type of Spanish they need for a translation project, they simply say “Just give me the best Spanish.” Once we explain that there is no “best,” they move on to request a “universal Spanish,” which is also an impossible task.

Spanish is the most widely spoken romance language and has the second most native speakers in the world. Most Spanish speakers live in Central and South America, and 21 countries list it as their national language. Spain has a population of 39 million, and Mexico has 100 million. Argentina has 36 million people and Chile 15 million.

With all the different Spanish speakers in the world, there is no one “best” type of Spanish. Spanish speakers from disparate areas recognize differences in a variety of ways. It is important to know the different types of Spanish and the best on suited to your target audience so that your project can be translated and localized accordingly.

Keep reading for an exploration of the differences between Spanish spoken by people around the world and how they impact yourtranslation, localization or interpreting project.

What is in a Name? Name Preferences for Spanish Variants

Where a person is from and how they feel about their traditions will dictate what they call the language they speak.

The Spanish used in Spain is frequently but inaccurately called “Castilian.” If you look at linguistic terminology reference guides, you will see that Castilian was a dialect from the area of Castile, and was based on the language spoken at that time. Castilian is therefore not a good term for modern-day Spanish. However, this does not stop some from referring to their language as Castilian or Castellano. If you look at a Spanish dictionary and see “Diccionario de la lengua Espanola,” it was probably produced in Spain. Latin Americans call their language Castellano.

When targeting translation or localization project for different audiences, it may be important to understand the sensitivity, which contributes to a desire for using the term Castellano rather than Espanola.

Spanish Pronunciation Differences—We Say “To-may-to” Or “To-mah-to” They Say “Yo” Or “Jo”

Unlike with languages such as Chinese, most Spanish-speaking people can understand each other even with the different Spanish variations. Pronunciation, however, is an immediate indicator of where the Spanish speaker is from.

There are a variety of pronunciation differences between variants. For example, people from Latin American nations pronounce “yo” like in yo-yo. In the Rio de la Plata, and in some parts of Chile however, they would say “jo.” Another difference is the pronunciation of z/s/th for certain words. In Spain, for the word taza (mug), they may say “tatha” whereas in Latin America they would pronounce “tasa.” In Spain, for the word canción (song), they may say “canthión, whereas in Latin America they would pronounce “canzión.”

While these differences in pronunciation do not stop your audience from understanding, they are an important consideration when hiring an interpreter or when having video or multimedia localized. Be sure that any Spanish speakers you hire have pronunciation that matches that of your target audience as much as possible.

Spanish Lexical or Terminology Differences

The largest differences between Spanish variants are lexical. Spanish-speakers from different places may use different terminology.

There are differences in Spanish variants between the specialized terminology they use, how much they translate, the use of indigenous terminology and how their type of Spanish has evolved. All of these differences mean that, when possible, a different translated version should be created for different locales.

Below are some important considerations for different types of Spanish.

Industry-specific Or Specialized Terminology

In some technical fields, such as medicine and chemistry, the differences between Spanish variants are not dramatic; however, the variations in computer science terminology are significant. For example, in Iberian Spanish, a computer is called “el ordenador” and in Castellano it would be “la computadora.”

How Much They Translate

Another consideration between types of Spanish is that in Spain they translate everything, whereas in Latin America they use more “Americanizations” for words. For example, a computer mouse in Spain is referred to as ratón whereas in Latin America it is simply referred to as mouse.

Indigenous Terminology

In Latin America, Mexico, the Andean nations and certain parts of Central Latin America, indigenous terminology exists. Some of these terms simply don’t exist anywhere else, so untranslatable terms occur.

How Their Spanish Has Evolved

Language evolves to produce new interpretations of old words and new words altogether. For example, old world terminology for car is “carro,” while the new world version is “automovil.” In other nations they use “coche,” but “coche” in Guatemala means pig. Ordinary everyday words can vary in the extreme.

After five centuries of geographic separation, the lexicons vary most in areas of terms that have been introduced since the Spanish Conquest and colonization. This is in part why technological or scientific terms differ so much between variants.

When supporting multiple locales, it is best to get the terminology agreed upon up front and have linguists from each region working together to resolve differences.

Spanish Differences By Location

During the translation process, small discrepancies between different regions can yield unanticipated and unintended results. It is important when requiring Spanish translation or interpreting services to consider the different Spanish dialects by location and region.

Latin American Dialects

There are five major regional variations or dialects of Latin America. These dialect regions can be generally summarized as being highland areas and lowland areas.

The variants spoken in highland areas are more similar to each other than the dialects spoken in the lowland areas and vice versa. Therefore, someone from an Andean nation would probably understand someone from Mexico more easily than someone from Argentina.

Central America is somewhat of a mixed zone, because it doesn’t fit in either of these categories. It is influenced by Mexico from the north, but also by the Caribbean from the east.

Below are the Latin American dialectical regions.

Mexico and the Adjacent Areas

Mexico, the Southwest United States, Republic of Guatemala

The Caribbean Areas

The Caribbean, including both Mexican coasts, Columbia, Venezuela, Puerto Rico, Cuba and the half of Hispaniola known as Santo Domingo

The Andes

The highlands of Colombia through Ecuador, Peru, Bolivia, NW Argentina and Northern Chile, except Lima


Chile is divided in linguistic usage and accentuation

Rio de la Plata

Argentina, Uruguay, and Paraguay. (This is probably the most disparate of all the Latin America regions in terms of vocabulary, inflection, lexicon and manner of address. It’s very distinct.)

Mexican Spanish vs. Iberian Spanish

Mexico has both the largest percentage and highest population of Spanish speakers. If you haven’t guessed by now, there are important differences between the Spanish in Mexico and that spoken in Spain.

Here are some interesting differences between Mexican Spanish and Iberian Spanish:

  • The use of stress on the possessive. In Spain, someone might say “es su problema,” while in Mexico the inflection would be on the second syllable: “es su problema.” This is similar to the way it would be said in America: “It’s your problem.”
  • Adding the suffix “eco” as a locative. E.g. guatemalteco
  • The frequency of adverbalizing adjectives. Canta suave; huele feo
  • The influence of substratum languages, especially Nahuatl (which contributed the words Cacao, chile, chocolate, tequila, coyote, and mezquite) and Quechua (which contributed coca, Inca, and llama)
  • Differences in common household words.

Spanish Variants In The US

The United States has substantial populations of Spanish speaking people. The states with the highest concentrations are listed below, in descending order:

  • California (Los Angeles, 3 million people)
  • Texas
  • New York (New York City, 2 million people)
  • Arizona
  • Colorado
  • New Mexico

Miami, Florida also contains a very high population of Spanish speakers (1 million people).

For translation or interpreting for consumer publications or for hospitals, court interpretations, legal documentation, etc., special care is required because the population groups that are represented in New York are not the same as those in California. The Spanish spoken in these areas varies widely.

Further confusion occurs for places like New York City or Miami. In these locations, there has been significant long-term integration. If one compares that group to the concentrated immigrant population in California, they are from a totally different socioeconomic and educational background. The Spanish-speaking Cuban-base in Miami cannot be communicated with the same as the newer Mexican populations in California.


After reading this blog, I hope that you have a better understanding of the differences that exist between types of Spanish and why it is impossible to just translate into one, universal “best” Spanish. It is important to be aware of these differences and to consider your target audience when you select the type of Spanish you will use for Spanish translation, localization and interpretingprojects.

Ideally your language service provider will discuss these Spanish differences with you and help you find the most suitable for your project. Be wary of any translation, localization or interpreting provider that does not question you on the type of Spanish you need for your next language project.
