We may live in a world of spell check and autocorrect, but there's one place precision still counts: The Scripps National Spelling Bee.
The 21st straight televised annual competition began in Oxon Hill, Md., on May 25, bringing together the world's best spellers aged 8 to 15.
How do you measure up to these brainy young adults? We invite you to test your spelling prowess on winning words from previous spelling bees.
Best of l-u-c-k!
