Indo-European languages
A language family spoken by 42% of the global population.
The Indo-European languages are a language family native to the north of the Indian subcontinent, most of Europe, and Greater Iran, with additional native branches in regions such as Armenia, parts of the southern Indian subcontinent, and mainland Southeast Asia. Historically, they were also spoken in Anatolia and Northwestern China. Over 3.4 billion people (42% of the global population) speak an Indo-European language as a first language, making it the most widely spoken language family. The family is significant to historical linguistics as it possesses the second-longest recorded history of any known family after Egyptian and the Semitic languages, and its analysis was central to the development of historical linguistics as an academic discipline in the 19th century.

Lore & Background
The Indo-European family is descended from a single prehistoric language, Proto-Indo-European, spoken during the Neolithic or early Bronze Age. The academic consensus supports the Kurgan hypothesis, which places the homeland in the Pontic–Caspian steppe. By the time of the first written records, Indo-European had already evolved into numerous languages across Europe and large parts of Asia. Written evidence appears during the Bronze Age in Mycenaean Greek and the Anatolian languages of Hittite and Luwian, with the oldest records being isolated Hittite words in Akkadian texts from the 20th century BC.
Reader's Guide
The Indo-European language family is the most widely spoken language family globally, with over 3.4 billion native speakers. The family includes ten major branches, eight still spoken, with Indo-Iranian being the largest. The reconstruction of Proto-Indo-European and the laryngeal theory, supported by the discovery of Hittite consonant ḫ, were major advances. The family's significance extends to understanding prehistoric migrations and cultural reconstruction, though no genetic relationships with other families are accepted by current academic consensus.
