"I knew it. I'd seen it before," Nandipati said of the winning word. "I just wanted to ask everything I could before I started spelling."
A coin collector and Sherlock Holmes fan, Nandipati aspires to become a physician or neurosurgeon. She also plays violin and is fluent in Telugu, a language spoken in southeastern India.
A semifinalist last year, Nandipati became the fifth consecutive Indian-American winner and 10th in the last 14 years, a run that began in 1999 when Nupur Lala won and was later featured in the documentary "Spellbound."
Wearing a white polo shirt with a gold necklace peeking out of the collar, the bespectacled, braces-wearing teen never showed much emotion while spelling, working her way meticulously through each word. Only a few of the words given to other spellers were unfamiliar to her, she said.
Her brother and parents joined her onstage after the victory, along with her maternal grandparents, who traveled from Hyderabad, India, to watch her. At one point as she held the trophy aloft, her brother, Sujan, pushed the corners of her mouth apart to broaden her smile.
Her father, Krishnarao, said Snigdha first showed an interest in spelling as early as age 4. As she rode in the car, he would call out the words he saw on billboards and she would spell them.
In the run-up to the bee, Nandipanti studied 6 to 10 hours a day on weekdays and 10-12 hours on weekends a regimen that she'll need to maintain to get through medical school, her father said.
"She says this is harder than being a neurosurgeon maybe," said her mother, Madhavi.
Stuti Mishra of West Melbourne, Fla., finished second after misspelling "schwarmerei" which means excessive, unbridled enthusiasm. While many spellers pretend to write words with their fingers, the 14-year-old Mishra had an unusual routine she mimed typing them on a keyboard. Nandipanti and Mishra frequently high-fived each other after spelling words correctly during the marathon competition.
Coming in third for the second consecutive year was Arvind Mahankali of Bayside Hills, N.Y. At 12, the seventh-grader was the youngest of the nine finalists. He has one more year of eligibility remaining, and he pledged to return.
"I got eliminated both times by German words," Mahankali said. "I know what I have to study."
Nandipati's prize haul includes $30,000 in cash, a trophy, a $2,500 savings bond, a $5,000 scholarship, $2,600 in reference works from the Encyclopedia Britannica and an online language course.
The week began with 278 spellers, including the youngest in the history of the competition 6-year-old Lori Anne Madison of Lake Ridge, Va. The field was cut to 50 semifinalists after a computer test and two preliminary rounds, and Lori Anne was two misspelled words away from a semifinal berth. The tiny, blue-eyed prodigy said she'd be back next year.
The highest-placing international speller was Gifton Wright of Spanish Town, Jamaica, who tied for fourth. This week, Scripps announced tentative plans for a world spelling bee with teams of spellers from dozens of countries. Once that gets off the ground, the National Spelling Bee would be closed to international participants.
Also tied for fourth were Nicholas Rushlow of Pickerington, Ohio, and Lena Greenberg of Philadelphia. The excitable Greenberg, a crowd favorite who ran delightedly back to her chair after each correct word, pressed her hands to her face and exclaimed, "Oh! Oh!" when she was eliminated.
Rushlow was making his fifth and final appearance in the bee, and this was his best showing. He got three words he didn't know one in the semifinals and two in the finals and managed to spell two of them correctly before the third one, "vetiver," tripped him up.
While he was satisfied with his performance, he's sad that his run is over.
"I'm a has-been now," Rushlow said.
