What Is the Oldest Language? the 15,000-Year-Old Words Humans Still Speak Today
By James H. Sterling
Q1: Is Tamil definitively older than Sanskrit?
A1: It depends entirely on whether antiquity is measured by archaeological texts or living vernacular survival. Sanskrit boasts older documented literary compositions, with the oral Rigveda dating back to roughly 1500 BCE. Tamil provides unbroken spoken continuity alongside literary works dating back to at least 300 BCE, maintaining a living community of over 80 million native speakers.
Q2: Why isn't Basque considered the oldest language in the world?
A2: Basque is Western Europe's oldest surviving language isolate, predating the arrival of Indo-European languages across the continent. Basque lacks written inscriptions older than Roman-era epigraphs from the first century CE, making Sumerian and Egyptian thousands of years older in the archaeological record.
Q3: How do linguists know a word is 15,000 years old?
A3: Evolutionary linguists use statistical frequency models and comparative phonetics. By measuring how often a word is spoken daily against the rate of phonetic shift across seven independent Eurasian language families, researchers found that high-frequency words like mother, who, spit, and thou share mathematical cognates tracing back to a common Eurasian ancestral population before the retreat of the glaciers.
