This resource contains linguistically annotated data for four official South African languages with a conjunctive orthography from the Nguni family (isiNdebele, isiXhosa, isiZulu and Siswati) as well as English. The data set is parallel for all five languages and the Nguni languages have been annotated for three different types of linguistic information: morphology, part-of-speech and lemmas. We have also included the protocols and tagsets used during annotation.
