Tau Origin and Meaning

The name Tau is a boy's name meaning "dusk, twilight; lion".

Tau, rhyming with cow, is a simple straightforward name with roots in two languages and cultures, the Kaurna language spoken by indigenous Australian people or the African Tswana language, a Bantu language spoken by five million people.

Grimes and Elon Musk have a son named Techno Mechanicus, who goes by Tau — a more wearable nickname than their other children, X and Y.
