Nunatak means the summit of a mountain that jets out from a glacier.

Winners: 2015’s Spelling Bee champions were Vanya Shivashankar, who spelled "Scherenschnitte" correctly, and Gokul Venkatachalam, who spelled "Nunatak."

Geoffrey Nunberg, a linguist at the University of California Berkeley, said the Bee was more of an intellectual exercise than a practical gauge of language skill since almost no one would ever use such recent Bee-winning words as “marocain,” “nunatak” and “guetapens.”

The 2014 bee produced the first tie in more than 50 years and then, after Vanya Shivashankar and Gokul Venkatachalam shared the 2015 championship – on the winning words “scherenschnitte” and “nunatak”, respectively – the organizers tweaked the rules.

This story corrects the spelling of “nunatak.”
