Algonquian; Pano-Takana family; Abkhaz, Abaza (both N. Caucasian) are SOV but have no case inflection.Languages of active alignment are purportedly SOV but have no case inflection (Klimov 1983: 73).Many Papuan languages have dominant SOV order, but there is very little evidence of fixed case system (Whitehead 1981).Ijo (Ijoid, Niger-Congo) is SOV but has no case marking (Hyman 1975b: 116-117; Hyman states that already the proto-language of the whole family was that way).Athabaskan languages are SOV but have no case marking (A. A. Kibrik, p.c.).SV & OV but no case distinguishing the two arguments in a transitive clause:Nama (Central Khoisan); Rashad (Kordofanian); Dan (Mande, Niger-Congo), Koklokuma Ijo (Ijoid, Niger-Congo), Supyire (Gur, Niger-Congo), Tunen (Bantoid, Niger-Congo); Koyraboro Senni Songhay (Songhay, Nilo-Saharan), Fur (Fur, Nilo-Saharan); Iraqw (Southern Cushitic, Afroasiatic), Tigre, Chala (both Semitic, Afroasiatic); Modern Armenian (Armenian, IE); Vogul (Ugric, Uralic); Ainu (isolate); Abkhaz (Northwest Caucasian); Elamite (extinct isolate); Dimasa (Baric, Tibeto-Burman), Mikir, Siyin Chin (Kuki-Chin-Naga, Tibeto-Burman), Nusu, Lisu, Yi (Burmese-Lolo, Tibeto-Burman); Tawala (Oceanic, Austronesian); Banz (East New Guinea Highlands), Asmat, Korowai, Wambon, Lomai (Central and South New Guinea), Amele (Madang, Trans-New Guinea), Hanga Hundi, Alamblak (Sepik), Rao (Ramu, Sepik); Gunwinggu (Gunwingguan, Australian), Burarra (Burarran, Australian), Laragia (Laragiyan, Australian), Marithiel, Marengar, Pungupungu, Maranungku, Matngala (Daly, Australian), Ungarinjin (Wororan, Australian); Slave, Sarcee, Navajo (Athabaskan); Santa Ana Keresan (Keresan); Mandan (Siouan); Takelma (Takelma); Seri (Hokan); Kiowa (Kiowa-Tanoan); Warao (isolate); Pirahã (Mura); Kawesqar (Qawesqar); Tucano (Tucanoan); Piaroa (Salivan); Wayapi (Tupi); Resigaro (Maipuran, Arawak); Muinane (Boran, Witotoan) (Dryer 2000).
Baker (1996: 505) mentions that overt case morphology is more common in verb-final languages than in verb-initial and polysynthetic languages. This is a commonly made, or commonly repeated, claim. Presumably, the cases that are supposed to be present in verb-final languages are grammatical ones, especially those for subject and object. But this would not need to be stipulated given that another universal is valid: IF there are non-grammatical cases, THEN there are also grammatical cases. In other words, having any cases at all would mean having grammatical cases. But that universal has exceptions: there are languages with local cases but no grammatical cases. If valid (though counterexamples abound), the question then would be WHY verb-finality as such should be an implicans of case, as opposed to the alternative, equally rigid orders of verb-initiality or verb-mediality. Verb-initiality would seem to come with verbal agreement/cross-reference more often than verb-mediality or verb-finality does, rendering further relational marking such as through case redundant. That would leave the difference between verb-finality and verb-mediality to account for.
