Afrikaans

South African language, developed out of the Dutch spoken in the country since the first Dutch East India Company settlement in the Cape, established in 1652. Afrikaans was considered a dialect of Dutch – known as “Cape Dutch” – until recognised as a language in the late 19th century. From the Dutch for “African”.

They forced us to do Afrikaans in high school.
