Burushaski is a language isolate — unrelated to any other known living language — spoken by around 90,000 people in the Hunza, Yasin, and Nagar valleys of Gilgit-Baltistan in northern Pakistan. It's one of the few language isolates in the modern world, alongside Basque, and is of considerable interest to historical linguists. The US Burushaski-speaking community is very small, with translation requests occasional and typically tied to Pakistani civil documents from northern Pakistan or academic translation of Burushaski-language materials. Burushaski has no widely standardised written tradition, so written documents are often transcribed into Urdu or English.
