Q:Information:  - A language isolate, in the absolute sense, is a natural language with no demonstrable genealogical (or "genetic") relationship with other languages, one that has not been demonstrated to descend from an ancestor common with any other language. Language isolates are in effect language families consisting of a single language. Commonly cited examples include Ainu, Basque, Korean and Sumerian, though in each case a minority of linguists claim to have demonstrated a relationship with other languages.  - Sumerian ("native tongue") is the language of ancient Sumer and a language isolate which was spoken in southern Mesopotamia (modern Iraq). During the 3rd millennium BC, a very intimate cultural symbiosis developed between the Sumerians and the Akkadians, which included widespread bilingualism. The influence of Sumerian on Akkadian (and vice versa) is evident in all areas, from lexical borrowing on a substantial scale, to syntactic, morphological, and phonological convergence. This has prompted scholars to refer to Sumerian and Akkadian in the third millennium BC as a "Sprachbund" (area of linguistic convergence).  - Iraq (, or ; '; '), officially known as the Republic of Iraq ('; ') is a country in Western Asia, bordered by Turkey to the north, Iran to the east, Kuwait to the southeast, Saudi Arabia to the south, Jordan to the southwest, and Syria to the west. The capital, and largest city, is Baghdad. The main ethnic groups are Arabs and Kurds; others include Assyrians, Turkmen, Shabakis, Yazidis, Armenians, Mandeans, Circassians, and Kawliya. Around 95% of the country's 36 million citizens are Muslims, with Christianity, Yarsan, Yezidism, and Mandeanism also present. The official languages of Iraq are Arabic and Kurdish.  - Sumer was the first urban civilization in the historical region of southern Mesopotamia, modern-day southern Iraq, during the Chalcolithic and Early Bronze ages, and arguably the first civilization in the world with Ancient Egypt and the Indus Valley. Living along the valleys of the Tigris and Euphrates, Sumerian farmers were able to grow an abundance of grain and other crops, the surplus of which enabled them to settle in one place.  - Sumerian literature is the literature written in the Sumerian language during the Middle Bronze Age . Most Sumerian literature is preserved indirectly , via Assyrian or Babylonian copies . The Sumerians invented the first writing system , developing Sumerian cuneiform writing out of earlier proto - writing systems by about the 30th century BC. The earliest literary texts appear from about the 27th century BC. The Sumerian language remained in official and literary use in the Akkadian and Babylonian empires , even after the spoken language disappeared from the population ; literacy was widespread , and the Sumerian texts that students copied heavily influenced later Babylonian literature .  - Mesopotamia ("[land] between rivers"; from Ancient Armenian  (Mijagetq); "bild ar-rfidayn" "miyn rodn"; "Beth Nahrain" "land of rivers") is a name for the area of the TigrisEuphrates river system, in modern days roughly corresponding to most of Iraq plus Kuwait, the eastern parts of Syria, Southeastern Turkey, and regions along the Turkish-Syrian and IranIraq borders.  - Babylonia was an ancient Akkadian-speaking state and cultural area based in central-southern Mesopotamia (present-day Iraq). A small Amorite-ruled state emerged in 1894 BC, which contained at this time the minor city of Babylon. Babylon greatly expanded during the reign of Hammurabi in the first half of the 18th century BC, becoming a major capital city. During the reign of Hammurabi and afterwards, Babylonia was called "Mt Akkad" "the country of Akkad" in the Akkadian language. It was often involved in rivalry with its older fellow Akkadian-speaking state of Assyria in northern Mesopotamia. Babylonia briefly became the major power in the region after Hammurabi (fl. c. 1792  1752 BC middle chronology, or c. 1696  1654 BC, short chronology) created a short-lived empire, succeeding the earlier Akkadian Empire, Third Dynasty of Ur, and Old Assyrian Empire; however, the Babylonian empire rapidly fell apart after the death of Hammurabi.  - A sprachbund ("federation of languages")  also known as a linguistic area, area of linguistic convergence, diffusion area or language crossroads  is a group of languages that have common features resulting from geographical proximity and language contact. They may be genetically unrelated, or only distantly related. Where genetic affiliations are unclear, the sprachbund characteristics might give a false appearance of relatedness. Areal features are common features of a group of languages in a sprachbund.  - In anthropology and geography, a cultural region, cultural sphere, cultural area or culture area refers to a geographical area with one relatively homogeneous human activity or complex of activities (culture). These are often associated with an ethnolinguistic group and the territory it inhabits. Specific cultures often do not limit their geographic coverage to the borders of a nation state, or to smaller subdivisions of a state. Cultural "spheres of influence" may also overlap or form concentric structures of macrocultures encompassing smaller local cultures. Different boundaries may also be drawn depending on the particular aspect of interest, such as religion and folklore vs. dress and architecture vs. language.    What is the relationship between 'sumerian literature' and 'culture'?
