- Senjecas is an Ursprache spoken in the homeland of Sefdaania (seven-river-land). Sefdaania was located in what is now eastern Europe stretching from the advancing or receding glacier (ȝeƣda̋a̋o, ice river) in the north to the Caspian Sea (ausma̋re, eastern sea), the Caucasus Mountains (ȝúsmarǧa̋ros, between sea mountains), the Pontic Mountains (k̨uǧa̋ros, shore mountains) and the Balkan Mountains (m̃esǧa̋ros, western mountains) in the south; from the Vistula River (kuðda̋a̋e, northern river), the Carpathian Mountains (þifǧa̋ros, far mountains) and the Balkan Mountains on the west to the Ural Mountains (v̌ééþn̨akı̋ȝo, world spine), the Ural River (m̃uida̋a̋e, border river) and the Caspian Sea on the east.
- Sefdaania means seven rivers and refers to the seven major rivers that flow through the land and empty into the Black Sea (m̃esma̋re, western sea) and the Caspian Sea. From west to east these are the Danube (mézm̃esda̋a̋e, great western river), the Dniester (m̃esda̋a̋e, western river), the Boh (pinda̋a̋e, small river), the Dnieper (meðda̋a̋e, middle river), the Don (ausda̋a̋e, eastern river), the Volga (méżausda̋a̋e, great eastern river), and the Ural.
- The language is now extinct.
- The language is being created (since c.1975) by Charles Brickner as a pre-PIE language for a fantasy culture. It is an a posteriori language, based mainly on PIE grammar and vocabulary, with a smattering of Proto-Altaic, Proto-Basque, Proto-Dravidian, Proto-Eskimo, Proto-Kartvelian, Proto-Uralic, Etruscan and Hittite to fill in the blanks, and some words of my own invention when the preceding do not supply.
