 Aramaic loan words, however, were limited to the 1st centuries of the 1st millennium BC and primarily in the north and middle parts of Mesopotamia, whereas Sumerian loan words were spread in the whole linguistic area.Beside the previous languages, some nouns were borrowed from Hurrian, Kassite, Ugaritic and other ancient languages.Since Sumerian and Hurrian, two non-Semitic languages, differ from Akkadian in word structure, only nouns and some adjectives (not many verbs) were borrowed from these languages.
