In South Africa, English has been spoken since 1820, co-existing with Afrikaans and various African languages such as the Khoe and Bantu languages. Today, about nine percent of the South African population speaks South African English (SAE) as a first language. SAE is a non-rhotic variety that tends to follow RP as a norm. It is one of the few non-rhotic English varieties that lack intrusive R. The second-language varieties of South Africa differ based on the native languages of their speakers.[300] Most phonological differences from RP are in the vowels.[301] Consonant differences include the tendency to pronounce /p, t, t͡ʃ, k/ without aspiration (e.g. pin pronounced [pɪn] rather than as [pʰɪn] as in most other varieties), while r is often pronounced as a flap [ɾ] instead of as the more common fricative.[302]
