Burushaski language is considered to be a unique and among the most ancient languages of the world. Despite new breakthroughs in ethnographic sciences, Burushaski defies classification and still remains a Language Isolate. (Dani, 1959) Presently it is spoken by the people living in three different valleys of Northern Areas of Pakistan: Hunza, Yasin and Nagar; and in parts of Kashmir India where a migrated minority resides. Two main dialects of Burushaski are spoken in the Hunza valley and the Yasin Valley. The former is divided into two closely related sub-dialects of Hunza and Nagar. Most of the languages spoken in Northern Areas of Pakistan i.e. Shina, Khwar, etc have their roots in Dardic languages (Dani, 2001) while Burushaski, together with Basque, Finnish and about a dozen other languages of the world, has been classified as a language isolate. The fact that its mother language has been lost and its sister languages have vanished make Burushaski an exceptionally unique part of the human heritage.After centuries of isolation, the society where this language was preserved is increasingly exposed to outside pressures and influences. With the opening of the area through the Karakoram Highway and other external influences, the language and culture face new challenges. Economic migration, increased awareness and influx of various cultures through travel and tourism have brought an immense cultural change. This economic ascendancy and cultural dominance has become a threat to Burushaski language. Since the phenomena of economic growth and cultural influx invariably go hand in hand, below I have narrated facts and examples, which cover both aspects simultaneously.In spite of the fact that the native inhabitants speak Burushaski as a means of communication, its inclusion in the school syllabus as a language is still missing. Urdu, being the national language, is the language of instruction and now with a flourishing tourism industry English has become another important language for the local people. Economic gains through trade have also encouraged the locals to learn and speak Chinese Turkish of the China border. Moreover, the political structure of the area necessitates the presence of army and government officials from the southern parts of the country, which entails the presence of other regional languages, which are mostly Pashtu or Punjabi.In this unending influx of other languages, Burusho have unconsciously started to drop their own ancient words and to use Urdu words instead. Due to the external influences, more than half the present-day Burushaski vocabulary is of Urdu, Khwar and Shina origin. In addition, over thirty thousand Burusho presently live in different cities of Pakistan for educational or economic purposes, whose environment forces them to use different languages. They have failed to retain Burushaski in their homes, and as a result a considerable number of these families, particularly children do not speak their mother tongue. All of these factors call for extraordinary measures to preserve and safeguard a language that not only represents the identity of a group of people but has scientific and heritage value globally.
