Swazi or siSwati is a Bantu language of the Nguni group spoken in Eswatini (formerly Swaziland) and South Africa by the Swati people.

[3] The official term is "siSwati" among native speakers; in English, Zulu, Ndebele or Xhosa it may be referred to as Swazi.

Siswati spoken in Eswatini can be divided into four dialects corresponding to the four administrative regions of the country: Hhohho, Lubombo, Manzini, and Shiselweni.

Unlike the variant in the south of Eswatini, the Mpumalanga variety appears to be less influenced by Zulu, and is thus considered closer to standard Swazi.

A feature of the standard prestige variety of Swazi (spoken in the north and centre of Eswatini) is the royal style of slow, heavily stressed enunciation, which is anecdotally claimed to have a 'mellifluous' feel to its hearers.

Verbs use the following affixes for the subject and the object: The following example of text is Article 1 of the Universal Declaration of Human Rights: Bonkhe bantfu batalwa bakhululekile balingana ngalokufananako ngesitfunti nangemalungelo.
