The most widely spoken language in South America is Spanish. As a result of colonization, the majority of South American countries, except Brazil, Suriname, Guyana, and French Guiana, primarily use Spanish as their official or national language. This wide usage makes it the dominant means of communication across the continent. In Brazil, Portuguese is the official language, resulting in a unique linguistic landscape where both Spanish and Portuguese are significant. With language shaping cultural identities and influences, Spanish plays a critical role in connecting diverse communities across South America and fostering regional communication and commerce.
