Marguerite Arbogast, 13, of Ludington Mich., spells her word during the second round of the Scripps National Spelling Bee in Oxon Hill, Md., Wednesday, May 29, 2013.

OXON HILL, Md. — Forty-one youngsters have advanced to the semifinals of the Scripps National Spelling Bee.

The 41 had the highest scores after Wednesday's onstage rounds and a computer test that included a vocabulary section for the first time in bee history.

The semifinals are Thursday afternoon. The finals are set for Thursday night, with the winner taking home more than $30,000 in cash and prizes.

Among the contenders is 13-year-old Arvind Mahankali, who finished third each of the past two years. Arvind breezed through his two words — "euphemism" and "belemnoid."
