My two favourite punny company names are Volvo and Audi.
Volvo is Latin for “I roll” which is a perfect name for a car manufacturer.
Audi is a little more convoluted. The company was originally named A. Horch & Cie. after its founder August Horch. “Horch” is also the German word for “listen” (imperative). The Latin imperative for “listen” happens to be “audi”. On another note: the four rings of the Audi logo represent the four companies that form today’s Audi company. They are DKW, Horch, Wanderer and NSU.
Does anyone else have any nice examples of punny company names?
