The Huns are often thought to have spoken a language that is related to the Turkic languages, although there is considerable debate among historians and linguists regarding the specifics.
Little direct evidence remains about the Hunnic language itself, as they left no written records. Most of what we know comes from the accounts of their interactions with neighboring peoples, such as the Romans and the Germanic tribes. The Huns may have spoken a language that included elements from earlier Central Asian languages, possibly influenced by the Turkic peoples, as well as some words from the languages of the conquered cultures.
It’s important to note that the Huns were a nomadic group, and their language could have varied significantly over time and across regions due to their interactions with various tribes and nations. Consequently, any assertions about their language must be approached with caution, keeping in mind the limited evidence available to us.
