World History

Etymology
The word history comes from the root weid- "know" or "see".
Ancient Greek ἱστορία means "inquiry" or "knowledge from inquiry", from ἵστωρ (hístōr) "judge" (from the Proto-Indo-European agent noun wid-tor: "one who knows"). It was in that sense that Aristotle used the word in his Περὶ Τὰ Ζῷα Ἱστορίαι (Perì Tà Zôa Ηistoríai "Inquiries about Animals"). The ancestor word ἵστωρ is attested early on in Homeric Hymns, Heraclitus, the Athenian ephebes' oath, and in Boiotic inscriptions (in a legal sense, either "judge" or "witness", or similar).
