Phuthi (Síphùthì)[4] is a Nguni Bantu language spoken in southern Lesotho and areas in South Africa adjacent to the same border.
[5] The closest substantial living relative of Phuthi is Swati (or Siswati), spoken in Eswatini and the Mpumalanga province of South Africa.
Although there is no contemporary sociocultural or political contact, Phuthi is linguistically part of a historic dialect continuum with Swati.
[1] Phuthi is spoken in dozens (perhaps many dozens) of scattered communities in the border areas between where the far northern Eastern Cape meets Lesotho: from Herschel northwards and eastwards, and in the Matatiele area of the northeastern Transkei; and throughout southern Lesotho, from Quthing in the southwest, through regions south and east of Mount Moorosi, to mountain villages west and north of Qacha (Qacha's Nek).
Other Phuthi-speaking areas (all given in Lesotho Sesotho orthography) include Makoloane [makolwani] and Mosuoe [musuwe], near Quthing, in south-western Lesotho; Seqoto [siǃɔtɔ] (Xhosa Zingxondo, Phuthi Sigxodo [siᶢǁɔdɔ]); Makoae [makwai] (Phuthi Magwayi) further to the east; and a number of villages north and west of Qacha's Nek.
In the aftermath of the siege, Phuthi people dispersed widely over what is contemporary southern Lesotho and the northern Transkei region, to escape capture by the colonial powers.
It is for this reason, it has been hypothesised, that Phuthi villages (including Mpapa, Daliwe, Hlaela, Mosifa and Mafura—all to the east of Mount Moorosi, in Lesotho) are typically found in such topographically mountainous regions, accessible only with great difficulty to outsiders).
But within southern Africa Phuthi is viewed ambivalently as being either a Nguni or a Sotho–Tswana language, given the very high level of hybridity displayed in all subsystems of the grammar (lexicon, phonetics, phonology, morphology, syntax).
Further, given the range of lexical, phonological and even low-level phonetic effects that appear to be shared almost exclusively with Swati, Phuthi can be classified uncontroversially as a Tekela Nguni language, that is, in the subset of Nguni that includes Swati, some versions of Southern Ndebele, and the Eastern Cape remnant languages, Bhaca and Hlubi.
[citation needed] Sustained field work by Simon Donnelly (UCT/Illinois/Wits Universities) in 1994–1995 among speech communities in Sigxodo and Mpapa (southern Lesotho) resulted in the discovery of a surprisingly wide range of phonological and morphological phenomena, aspects of which are unique to Phuthi (within all of the southern Bantu region).
Phuthi has a system of click consonants, typical for nearly all Nguni, at the three common articulation points: dental, alveolar, and lateral.
But the range of manners and phonations, or click 'accompaniments', is relatively impoverished, with only four: tenuis c q x, aspirated ch qh xh, voiced gc gq gx, and nasal nc nq nx.
Like all Nguni languages, Phuthi also displays phonetically rising and falling syllables, always related to the position of a depressed syllabic nucleus.
This phenomenon results in what is analysed at one level as massive and sustained violations of locality requirements on a H tone domain arising from a single H tone source, e.g. surface configurations of the type HLH (in fact H L* H) are possible where all H syllables emanate from a single underlying H source, given at least one L syllable being depressed.
Such tone/voice configurations lead to grave problems for any theoretical phonology that seeks to be maximally constrained in its architecture and operations.
The last two phenomena are non-tonal suprasegmental properties which each take on an additional morphological function in Phuthi: The vocalic property breathy voice/depression is separated from the set of consonants that typically induce it, and is used grammatically in the morphological copulative – similar to the Swati copula – and elsewhere in the grammar too (e.g. in associative prefixes formed from 'weak' class noun prefixes 1,3,4,6,9).
