Sumerian cuneiform in the context of "Text corpus"

The history of writing traces the development of writing systems and how their use transformed and was transformed by different societies. The use of writing – as well as the resulting phenomena of literacy and literary culture in some historical instances – has had myriad social and psychological consequences.

Each historical invention of writing emerged from systems of proto-writing that used ideographic and mnemonic symbols but were not capable of fully recording spoken language. True writing, where the content of linguistic utterances can be accurately reconstructed by later readers, is a later development. As proto-writing is not capable of fully reflecting the grammar and lexicon used in languages, it is often only capable of encoding broad or imprecise information.

The Harappan language, also known as the Indus language, is the unknown language or languages of the Bronze Age (c. 3300 to 1300 BC) Harappan civilization (Indus Valley civilization, or IVC). The Harappan script is yet undeciphered, indeed it has not even been demonstrated to be a writing system, and therefore the language remains unknown. The language being yet unattested in readable contemporary sources, hypotheses regarding its nature are based on possible loanwords, the substratum in Vedic Sanskrit, and some terms recorded in Sumerian cuneiform (such as Meluhha), in conjunction with analyses of the Harappan script.

There are some possible loanwords from the language of the Indus Valley civilization. Meluḫḫa or Melukhkha (Sumerian: 𒈨𒈛𒄩𒆠 Me-luḫ-ḫa) is the Sumerian name of a prominent trading partner of Sumer during the Middle Bronze Age. Its identification remains an open question, but most scholars associate it with the Indus Valley Civilisation. Asko Parpola identifies Proto-Dravidians with the Harappan Culture and the Meluhhan people mentioned in Sumerian records. In his book Deciphering the Indus Script, Parpola states that the Brahui people of Pakistan are remnants of the Harappan culture. According to him, the word "Meluhha" derives from the Dravidian words mel ("elevated") and akam ("place"). Parpola also relates Meluhha with Balochistan, which he calls the "Proto-Dravidian homeland". He also relates Meluhha with the transient word Mleccha, a Vedic word used to mean "barbarian" and used by the incoming Aryan speaking population for the native Harappan population.

Sumerian literature constitutes the earliest known corpus of recorded literature, including the religious writings and other traditional stories maintained by the Sumerian civilization and largely preserved by the later Akkadian and Babylonian empires. These records were written in the Sumerian language in the 3rd and 2nd millennia BC during the Middle Bronze Age.

The Sumerians invented one of the first writing systems, developing Sumerian cuneiform writing out of earlier proto-writing systems by about the 30th 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. The basic genres of Sumerian literature were literary catalogues, narrative/mythological compositions, historical compositions, letters and legal documents, disputation poems, proverbs, and other texts which do not belong to these prior categories.

Lugal (Sumerian: 𒈗) is the Sumerian term for "king, ruler". Literally, the term means "big man". In Sumerian, lú "𒇽" is "man" and gal "𒃲" is "great", or "big".

It was one of several Sumerian titles that a ruler of a city-state could bear (alongside en and ensi, the exact difference being a subject of debate). The sign eventually became the predominant logograph for "King" in general. In the Sumerian language, lugal is used to mean an owner (e.g. of a boat or a field) or a head or chief (of a unit, such as a family).
