An ancient language is any language originating in times that may be referred to as ancient. There are no formal criteria for deeming a language ancient, but a traditional convention is to demarcate as "ancient" those languages that existed prior to the 5th century.[1] Linguist Roger Woodward has said that "[p]erhaps, then, what makes an ancient language different is our awareness that it has outlived those for whom it was an intimate element of the psyche".[1]
By this definition, the term includes languages attested from ancient times in the list of languages by first written accounts, and described in historical linguistics, and particularly the languages of classical antiquity, such as Tamil, Ancient Greek, Sanskrit and Latin. The term may include some extinct languages.
