Fresno, California-A sixth-grader from Fresno, California, Ananya won the spelling competition after competing for 12 hours and spelled 35 words correctly.

Her rival was Rohan Rajeev, another 14-year-old Indian- American student from Oklahoma, misspelled the word 'marram' which is a coarse grass found on sandy beaches. Ananya's victory underscores the overwhelming dominance of Indian-Americans in the annual intense competition. "Congratulations to our 2017 Scripps National Spelling Bee Champion, Ananya Vinay.

What a fantastic performance!,"the National Spelling Bee's official account tweeted. "She played to win and win she did. Ananya Vinay takes home the 2017 Scripps National Spelling Bee Champion title and trophy," it said.

More than 11 million youngsters aged between six and 15 from all 50 US states, US territories such as Puerto Rico and Guam and countries such as Japan and Jamaica had entered the nerve-racking competition.

Ananya and Rajeev were the last two standing of the initial 291 spellers.

Ananya captured the 90th championship title by correctly spelling "marocain", which is a dress fabric made from silk or rayon, during the 36th round of the annual competition held at the Gaylord National Resort and Convention Center in suburban Washington.

"It's like a dream come true, I'm so happy right now. I just focused on my word and tried to spell it right," said Ananya upon receiving the winner's trophy.

In a post-victory interview, Ananya told reporters she was able to recognise one of the final words as it had been mentioned in her social studies book.

"You can find words in interesting places," she was quoted as saying by the 'USA Today'.

Ananya is the 13th consecutive Indian-American winner of the competition and the 18th of the past 22 winners with Indian heritage, a run that began in 1999 with Nupur Lala's victory, which was featured in the documentary "Spellbound."

Ananya honed her skill in highly competitive national bees that are limited to Indian-Americans, the North South Foundation and the South Asian Spelling Bee, although she did not win either.

Ananya's victory broke the Bee's three-year streak of ending in a tie. She wins USD 40,000 in cash, a trophy and other prizes, the report said.

Asked about her competitor, Rohan, Ananya said, "It was interesting to go back and forth for so many rounds".

The annual contest opened on Tuesday with a record 291 spellers from across the country and the globe.

The field was narrowed to 40 finalists on Wednesday, based upon two oral rounds of spelling and the results of a written spelling and vocabulary test.

By yesterday afternoon, just 15 spellers were still standing and went on to compete for the championship whose final rounds were broadcast live.

The National Bee is a high-profile, high-pressure endurance test as much as a nerd spelling match and spellers spend months preparing for it.
