Languages with only a 2nd person dual: Dizi (W. Omotic, Afro-Asiatic), independent pronouns and prefixal possessives have dual only in 2nd person (mentioned in Plank 1989: 303-4, but see caveat in Counterexamples to #567).Languages with only a 3rd person dual: Tunica (isolate possibly remotely related to Algonquian), in which it only occurs in the masculine, and Old Akkadian (Semitic, Afro-Asiatic) in which it is only present in the verb subject inflection (mentioned in Greenberg 1988: 1).South Arabian (Afro-Asiatic), in which dual with nouns and verb agreement is restricted to 3rd person.Hupa (Athabaskan), where the indirect way of expressing duality, by means of simultaneously marking verbs as plural and non-plural, is restricted to 3rd person subjects (mentioned in Plank 1989: 303-4).
1. Cf. #1137. 2. Cf. Greenberg’s statement (#1409): The existence of a 2nd person dual pronoun seems to always imply that of a 1st person dual, whether with or without the inclusive-exclusive distinction, and/or a 3rd person dual.
