ukr

ukr is the ISO 639-3 code for the Ukrainian language. It is used in linguistic databases, cataloging systems, and language tagging to identify Ukrainian as a distinct language.

Ukrainian is an East Slavic language within the Indo-European family. It is native to Ukraine and is the country's official state language. The language is written in a Cyrillic script with 33 letters and exhibits dialectal variation across regions. The standard form of Ukrainian emerged from historical varieties and is used in education, media, literature, and government.

Historically, Ukrainian developed from Old East Slavic in the territories of the medieval Kievan Rus' and later developments; its modern standardization took place mainly in the 19th and 20th centuries, with further reforms in the 20th century. The language has a rich literary tradition, with notable writers such as Taras Shevchenko contributing to its modern standard form.

Geographically, most speakers reside in Ukraine, with sizable communities abroad in Canada, the United States, Poland, and other countries. Ukrainian is widely used in public life in Ukraine, including education, media, and government; regional variation exists, and Russian is also widely spoken in some areas and contexts.

Beyond Ukraine, the 'ukr' code is used in language tagging for technology, libraries, and data exchange. In internet and software contexts, tags such as 'ukr' or 'uk-UA' help specify Ukrainian language content.
