Is it true that languages related a long time ago exhibit systematic correspondences distinct from unrelated ones?
Yes. Languages that share a common genealogical origin exhibit systematic sound correspondences and cognates, which form the cornerstone of historical linguistics.
Verdict: SUPPORTED · 6 sources for, 0 against · Last checked
The analysis
Papers 0, 2, 3, 4, 9, and 10 all support the claim that related languages exhibit systematic sound correspondences and regularities used to determine genealogical relationships. There are no papers refuting this principle. Therefore, the balance verdict is SUPPORTED.
