The US National Spelling Bee champion has been named as Snigdha Nandipati.
The 14-year-old from San Diego is the fifth consecutive Indian-American winner and the 10th in the last 14 years.
She spelled "guetapens", a French-derived word that means ambush, snare or trap, to take the title. Calm and collected throughout, she beat eight other finalists in the nerve-wracking competition.
Snigdha is an avid reader and coin collector who aspires to become a psychiatrist or neurosurgeon. She plays the violin and is fluent in Telugu.
Stuti Mishra of West Melbourne, Florida, finished second after misspelling "schwarmerei", which means to be overly enthusiastic.
Prizes for winning the 85th Scripps National Spelling Bee include 30,000 dollars (£19,400) in cash, a trophy, a 2,500 dollar (£1,600) savings bond, a 5,000 dollar (£3,232) scholarship, reference works from the Encyclopedia Britannica worth 2,600 dollars (£1,680) and an online language course.
