Genetic Relationships between Languages (Series)
語言之間的「遺傳關係」（系列）
Linguistics tells us that languages naturally evolve and change through time. Because of this, languages have “histories.”
The languages that exist today (“modern languages”) all evolved throughout their respective histories to arrive at their current forms, and they continue to evolve and change constantly.
Once we understand that all modern languages have histories, we can go on to explore the concept of “historical family relationships”—or “genetic relationships”—between languages.
Part 1:
Languages have “family histories” too
語言學讓我們知道，語言是會隨著時間自然地發展和演變的。因此，每個語言都擁有自身的「歷史」。
現今存在的各種語言（下稱「現代語言」）都是經歷了自己的發展史才演變成現有的模樣，而且這種發展和演變還會一直持續。
既然知道所有現代語言都有自身的歷史，我們便可以進一步探索各種語言之間的「歷代家族關係」或「遺傳關係」。
