Most people on which continent speak either portuguese or spanish?

The continent where most people speak either Portuguese or Spanish is South America.

Here's why:

* Portuguese: Brazil, the largest country in South America, is the only country in the continent where Portuguese is the official language.

* Spanish: The majority of South American countries, including Argentina, Colombia, Chile, Peru, Bolivia, Ecuador, Venezuela, Uruguay, and Paraguay, have Spanish as their official language.

While Portuguese and Spanish are spoken on other continents, they are not as dominant in terms of the number of speakers as they are in South America.
