Marked nominative languages are relatively rare. They are well-documented in only two regions of the world: in northern Africa, where they occur in many languages of the
Cushitic,
Omotic and
Berber branches of the
Afroasiatic family, as well as in the
Surmic and
Nilotic languages of the
Eastern Sudanic family; and in the southwestern United States and adjacent parts of Mexico, where they are characteristic of the
Yuman family. Other languages interpreted by some authors as having a marked nominative system include
Igbo,
Aymara and
Wappo. It is also proposed that marked-nominative alignment can be reconstructed for the ancestor of the
Afroasiatic languages, viz.
Proto-Afroasiatic. In Yuman and many of the Cushitic languages, however, the nominative is not always marked for reasons that are not known. There may, therefore, be not a strict case system but a reflection of discourse patterns or other non-
semantic parameters. However, the Yuman language
Havasupai is reported to have a purely syntactic case system, with a suffix
-č marking all subjects of transitive and intransitive verbs but not of the copula; in the Nilotic language
Datooga, the system is also reported to be purely syntactic. As in many Nilotic languages, Datooga case is marked by tone. The absolutive case has the unpredictable tone of the citation form of the noun, but the nominative is marked by a characteristic tone that obliterates the lexical tone. The tone is high for words of three syllables or less; for words with four or more syllables, the ends of the word have high tone, with a low tone in the middle of the word. In most African languages with a marked nominative, the nominative is used for subjects following the verb, the absolutive with the copula, with subjects in focus position before the verb, and in all other situations.
Okinawan, a
Japonic language, is generally a marked nominative language where nominative subjects are marked with the case particles
ga or
nu depending on their level of
animacy. Unmarked nouns are by default in the accusative case. However, some verbs of existence and emergence may also have optionally unmarked nominative subjects.
Savosavo, a
papuan languague spoken in
Soloman Islands, marks the nominative case with a clitic at the end of the noun phrase, while there is no accusative case marker. ==See also==
