The Scripps National Spelling Bee is only a week away, and to celebrate the occasion, dictionary writers Merriam-Webster and Babbel — and app that helps people learn new languages — has teamed up to analyze 10 years-worth of words that knocked out spelling bee finalists. The analysis included almost 400 words, and found that most often competitors were eliminated by words that have their origins from classical languages. Specific fields such as scientific, medical, and legal terms often trace their origins back to Greek or Latin. In particular, words pertaining to nature and natural science caused a whopping 38% chance of being misspelt.

“English has always borrowed words from other languages, and once they are found in our dictionaries they are considered to be English words,” said Peter Sokolowski, an editor at Merriam-Webster. It’s not a huge surprise then that most English speakers will find these “foreign” words much harder to spell.
