3. Spanish, Hispanic, Latino, Latinx, Mexican – Which One Is It? Not That Simple

Because these are labels that were forced on Latinxs upon their arrival to the US, the answer as to how people from different Latin American countries identify varies depending on who you ask.

With that in mind, here’s a primer:

Spanish people come from Spain, so it would be incorrect to refer to someone from Latin America or the Spanish-speaking Caribbean as Spanish.

Hispanic, on the other hand, refers to people who descend from Spanish-speaking countries (Brazilians and Haitians, for example, wouldn’t be considered Hispanic).

It’s important to note, however, that many people from Spanish-speaking countries resist the Hispanic categorization, viewing it as a marker that connects them directly to their colonizers – that is, the Spanish.

Instead, they may prefer Latino, which, while referring to all the countries in Latin America, including Brazil and Haiti, also ties these people together through a history of colonization.

Latinx is similar to Latino, but the “x” erases gender, making the category inclusive of men, women, agender, gender non-conforming, genderqueer, and gender-fluid people.

Finally, it bears repeating that people in Latin America neither refer to themselves as Latinx nor Hispanic. These, again, are words placed on them soon after their arrival in the US.

For many people in Latin America, they are just Cuban, Ecuadorian, Bolivian, or whichever country or indigenous population they belong to.
