So this might be random but Triptych is a real word! Maybe this doesn't surprise our authors, but I had assumed it was well a neat sounding made up Evil Corporation name!
But as was reading a food blog. (i'm so addicted to these)and they used it in a sentence! so I googled it... and it references the tri-folded paneled art work that is hinged.... or better explained here
Feel a little like I just learned as SAT word.
