Sumerian language. Sumerian language, language isolate and the oldest written language in existence. First attested about 3100 bc in southern Mesopotamia, it flourished during the 3rd millennium bc. About 2000 bc, Sumerian was replaced as a spoken language by Semitic Akkadian (Assyro-Babylonian) but continued in written usage almost to the end of the life of the Akkadian language, around the beginning of the Christian era.
A constructed language is a language--such as Esperanto, Klingon, and Dothraki--that has been consciously created by an individual or group. A person who creates a language is known as a conlanger. The term constructed language was coined by linguist Otto Jespersen in An International Language, 1928. Also known as a conlang, planned language, glossopoeia, artificial language, auxiliary language, and ideal language. The grammar, phonology, and vocabulary of a constructed (or planned) language may be derived from one or more natural languages or created from scratch.
