The letter TET makes a “t” sound just like the letter TAV. Over the years, my students have helped me come up with multiple ways to remember TET. TET is shaped like an uppercase “U” with a diagonal line coming down about halfway from the far right point of the “U”. Originally, I had called it tugboat TET but I really had no idea what a tugboat looked like and neither did any of my students. It’s still quite catchy though, so even without a clear vision of a tugboat in mind, it will stick in your brain. If not, we can also remember TET as tub TET because it resembles a hot tub or tulip TET.
