 This group distinguishes itself from the Northwest and South Semitic languages by its subject–object–verb word order, while the other Semitic languages usually have either a verb–subject–object or subject–verb–object order.This novel word order is due to the influence of the Sumerian substratum, which has an SOV order.Additionally Akkadian is the only Semitic language to use the prepositions "ina" and "ana" (locative case, English "in"/"on"/"with", and dative-locative case, "for"/"to", respectively).
