The chief Sebituane, born some hundred and twenty years ago, was a Mosuto, the son of a great crazy woman-chief known as Mantatisi. He carried his Sesuto tongue with him on the amazing journey he made with half his tribe across Bechuanaland to Lake Ngami and the Zambezi. Sechuana or Sesuto was the Court language in Barotseland when Livingstone first reached the Upper Zambezi in 1851. As the years rolled by, and after the Makololo (Basuto) dynasty had given place to a restoration of the Aluyi chieftainship, the original Sesuto spoken by Sebituane and well understood by Livingstone (who could converse in it freely) became greatly changed. It has remained the governing language of Barotseland and has succeeded almost in replacing and killing the remarkable Siluyi of the old rulers; and neither of the beautiful languages of the Tonga-Subia group of Southern and South-Eastern Barotseland has been allowed to take its place. In Sikololo the pronunciation is much simplified. The rough guttural combination _kx_—of Sechuana-Sesuto gives way to the simple _k_; a hiatus formed by a dropped consonant is filled by _h_; _ts_ is generally changed to _z_; _e_ in the prefixes becomes _i_; _f_ which had become _h_ in Sesuto is generally replaced; the uncouth _tl_, _tlh_ or the aspirated _th_ and _kh_ return to the simple _t_ and _k_; and in general the pronunciation of Sikololo is brought into conformity with the harmonious phonology of the Zambezi languages. A far more interesting tongue is _Siluyi_, the nearly extinct language of the Aluyi; in its older form, that is to say, as it was spoken round about Lialui (the original governing centre, near the left bank of the Zambezi, in about 15° 15´). Here it was a stately language, using preprefixes, and possessing all the seventeen customary prefixes of the Bantu languages. The second (_Ba_-) and eighth (_Bi_-) of these were in an abbreviated form, because the Luyi tongue had rather a dislike to an initial _b_, though it turned the sixteenth prefix—_Pa_- into _Ba_-, following a practice which recurs a good deal in the Angola tongues. The principal form in which I have presented this language in the First Volume of my _Comparative Study_ is derived from the studies of Luyi (Siluyi) compiled some twenty to twenty-five years ago by the Rev. E. Jacottet, of the French Protestant Mission. It was soon evident, when the British South Africa Co. officials got to work, that there was at least one separate dialect of Luyi spoken to the East and North-East of the main Zambezi. This was the _Si-kwango_ or _Si-kwangwa_, a tongue in which the preprefixes are dropped. Si-kwangwa seems still to be a living speech among the people in the East-Central part of Barotseland; but the much nobler Luyi of the Zambezi vicinity is dying out, even among the natives of Luyi stock, dying out in favour of mongrel Sikololo.
