DEV SHAH: Spelling is about roots, language. I genuinely loved getting a word I didn't know and having all this information - it was like a detective case: you have the language of origin, the definition, alternate pronunciations, roots;  it's like witnesses and having details to a crime scene, forensics. And, you know, it was just me piecing out together, doing what I love, in front of millions of people, shining on a stage, cameras, and still getting a lot from it. 
HZ: And you got to do all that detective work in ninety seconds. 
DEV SHAH: Exactly.
