[Q]: Passage: The term "Sumerian" is the common name given to the ancient non-Semitic inhabitants of Mesopotamia, Sumer, by the Semitic Akkadians. The Sumerians referred to themselves as ùĝ saĝ gíg-ga (cuneiform: 𒌦 𒊕 𒈪 𒂵), phonetically /uŋ saŋ giga/, literally meaning "the black-headed people", and to their land as ki-en-gi(-r) ('place' + 'lords' + 'noble'), meaning "place of the noble lords". The Akkadian word Shumer may represent the geographical name in dialect, but the phonological development leading to the Akkadian term šumerû is uncertain. Hebrew Shinar, Egyptian Sngr, and Hittite Šanhar(a), all referring to southern Mesopotamia, could be western variants of Shumer.
