Pre-Indo-European languages

The oldest Indo-European language texts are Hittite and date from the 19th century BC in Kültepe (modern eastern Turkey), and while estimates vary widely, the spoken Indo-European languages are believed to have developed at the latest by the 3rd millennium BC (see Proto-Indo-European Urheimat hypotheses).

[1][2][3] A handful of the pre-Indo-European languages are still extant: in Europe, Basque retains a localised strength, with fewer than a million native speakers, but the Dravidian languages remain very widespread in the Indian subcontinent, with over 200 million native speakers (the four major languages being Telugu, Tamil, Kannada and Malayalam) and the Brahui that stretches into modern Iran.

In much of Western Asia (including Iran and Anatolia), the pre-Indo-European, Hurrian/Caucasian, Semitic languages, Dravidian and language isolates have survived to the present day, although Elamite has been entirely supplanted.

In 1953, the linguist Johannes Hubschmid identified at least five pre-Indo-European language families in Western Europe: Eurafrican, which covered North Africa, Italy, Spain and France; Hispano-Caucasian, which replaced Eurafrican and stretched from Northern Spain to the Caucasus Mountains; Iberian, which was spoken by most of Spain prior to the Roman conquest of the Iberian peninsula; Libyan, which was spoken mostly in North Africa but encroached into Sardinia; and Etruscan, which was spoken in Northern Italy.

In particular, the vast majority of the major languages spread by colonialism have been Indo-European (the major exceptions being Arabic, Turkish and Mandarin Chinese), which has in the last few centuries led to superficially similar linguistic islands being formed by, for example, indigenous languages of the Americas (now surrounded by English, Spanish, Portuguese, Dutch, and French), as well as of several Uralic languages (such as Mordvin, Udmurt, Mari, Komi etc) and Caucasian languages (such as Circassian, Abkhaz, Nakh-Dagestanian languages etc) now surrounded by Russian.
