Brazilian German

The German-based varieties spoken by German Brazilians together form a significant minority language in Brazil. "Brazilian German" is strongly influenced by Portuguese and to a lesser extent by Italian dialects as well as indigenous languages. German dialects are particularly strong in Brazil's South and Southeast Regions. According to Ethnologue, ca. 3 million people in Brazil speak Riograndenser Hunsrückisch, 1.5 million Standard German (likely including Pommersch), and 8,000 Plautdietsch.

German speakers from Germany, Switzerland and Austria make up the largest group of immigrants after Portuguese and Italian speakers. They tended to preserve their language longer than the speakers of Italian, which is closer to Portuguese. Consequently, German was the second most common family language in Brazil at the 1940 census. However, even in areas that are still dominated by German speakers, most are bilingual. Today, German is increasingly cultivated as a cultural heritage, and several municipalities have recently given co-official status with Brazilian Portuguese to one Brazilian variant or another of it.

Riograndenser Hunsrückisch is the most significant variant, and the term is sometimes used so as to include all forms of Brazilian German. It is particularly well represented in the two southernmost states, Rio Grande do Sul and Santa Catarina. But especially in Espírito Santo there are significant pockets whose dialect is based on East Low German (Pommersch), and some other dialects can be found locally due to 20th century immigration.
