79th Annual Scripps National Spelling Bee Contest on ESPN

I was watching the 79th Annual Scripps National Spelling Bee Contest (held in Washington D.C.) on ESPN this morning in which 8th graders were being asked to spell words in English. English words of German origin made some of the contestants including a contestant of Indian origin bow out. In the last round, there were only two girls and they were being asked to spell Championship words (probably those words which had been used in the same contest earlier).
Have a look at the words and find out how many have you even heard of. Katharine Close went on to win it.
