Old Akkadian.
3 du. pronominal suffixes are also present in Arabic (see
-humā) and MSA (see Mhr.
-hi). Akkadian and Arabic forms are based on the plural masculine form, while in MSA 3 du. pronominal suffixes are formed on the basis of the singular. Non-Semitic Afroasiatic evidence (see Eg. -sny) points at the primary nature of Akkadian-Arabic picture (Kogan 2009:69).
