The word “Corriedale”

defines a type of sheep from New Zealand. It also is the word that knocked out Orlando spelling-bee champ Siyona Mishra in the fifth round of the national spelling bee in Washington, D.C.

An Orlando eighth-grader made it to the fifth round in a national spelling bee before getting knocked out Thursday — by a New Zealand sheep.

Siyona Mishra, 13, misspelled the word a breed of sheep developed in New Zealand, during the finals of the Scripps National Spelling Bee.

She was one of 40 finalists in the competition, which started earlier this week with 291 spellers.

Siyona, speaking by phone from Washington, D.C., said the word was especially difficult as none of the questions she asked — such as its origin — provided her any real clues to its spelling.

She was disappointed, she said, as she’d studied and knew how to spell all the other words used in the previous rounds Thursday.

Siyona got hooked on spelling after she entered, and won, her first bee as a fourth grader.

Siyona is a student at Orlando Science Middle/High School. This was her second appearance on the national spelling stage. She competed in 2015, too, finishing ninth.

Both times, she first won the regional bee sponsored by the Orlando Sentinel, which included a paid-for trip to the national bee in Washington, D.C..

In the Orlando spelling bee, she competed in 17 rounds, winning on the word which means to become gangrenous.
