In biblical tradition, the story of the Tower of Babel, found in Genesis 11:1–9, serves as an etiological myth to explain the origin of linguistic diversity.12

According to the narrative, humanity originally shared a single language. When the people gathered in the land of Shinar to build a city and a tower reaching toward the heavens, they were motivated by a desire for fame and a wish to remain centralized, which some interpret as an act of hubris and defiance of the divine command to populate the earth.12

To thwart this project, God intervened by confusing the builders' speech so they could no longer understand one another. This divine act caused the construction to cease and resulted in the people being dispersed across the globe, thereby accounting for the existence of many different languages. The name "Babel" itself is linked in the text to the Hebrew word balal, meaning "to confuse," highlighting the narrative's focus on the sudden fragmentation of human communication.23
