12 incredibly hard-to-spell words that have won the Scripps National Spelling Bee

The Scripps National Spelling Bee finals air Thursday night on ESPN, and the winning word could be one you've never even heard, let alone know how to spell.

In a rare tie last year, Texas teenager Ansun Sujoe gave up on trying to pronounce the winning word, just saying "whatever" and proceeding to spell it.

That word was feuilleton, a section of a European periodical designated for gossip and other topics that would appeal to the general reader (sort of like the New York Times' style section).

The other winning word, stichomythia, means a dispute delivered by actors in alternating lines, like in classical Greek drama.

The winning words weren't always this arcane or difficult to spell. In 1932, for example, the winning word was knack. The word interning won in 1936, and therapy took the prize four years later. Since the 1950s, though, the Bee has featured words like cymotrichous that might have educated people scratching their heads.

We looked back at some of the biggest head-scratchers that won the Bee:
