语言一经确立,就能够保留远古时代的痕迹,成为遥远过去的有力证据。它是考察民族起源奥秘的宝贵材料。但是对于民族起源的研究来说,使用的材料大多是语言中最不固定的东西——词汇。词汇是语言中最多变的,因此,语音结构、语音频率及其关系就具有无可比拟的价值。在两千年中,包括从雅库特语到土耳其语、从鞑靼语到撒拉语的诸突厥语言分布于亚洲和欧洲的广大地区,但它们的语音统计比值几乎没有发生变化。例如,在每一种语言中,95%的p音部直接跟在元音的后面(俄语为40%)。用这种方法可以测量出语言之间的“距 Once the language is established, it will be able to retain the traces of ancient times and become a powerful evidence of the distant past. It is a valuable material for examining the mysteries of the origins of the nation. But for the study of ethnic origin, most of the materials used are the most unfixed in the language - vocabulary. Vocabulary is the most variable in the language, so the phonetic structure, phonological frequency and their relationship have unparalleled value. For two millennia, Turkic languages, from Yakut to Turkish, from Tatar to Salar, are widely distributed in Asia and Europe, but their voice-statistics ratios have hardly changed. For example, in each language, 95% of p-voices follow directly behind the vowel (40% in Russian). In this way can measure the "distance between languages
