Congratulations to Kavya Shivashankar, the 13-year-old winner from Olathe, Kansas. Excellent job.
On a separate note, one of the earlier words in the finals was "brachyology," which sounds a lot like the word "bracketology" of which I have previously posted.
A brachyology is defined by reference.com as: a figure of speech that is an abbreviated expression. An example is the omission of "good" in "good morning."
