tres (Latin)

Where does "tres" come from?

The Latin word "tres" descends from the Proto-Indo-European root "*tréyes," through the intermediate Proto-Italic stage "*trēs." This ancient number is a linguistic sibling to terms like the Ancient Greek "treîs" and the Old English "þrēo," which eventually evolved into the modern English "three." Scholars have long speculated that this root once contained imagery related to the fingers or tips, connecting it to the earliest human methods of counting.
