There once was a time when you could win the Scripps National Spelling Bee, now underway, by correctly spelling "initials."

Not anymore.

Last year, the co-champions won with "feuilleton" (the part of a European newspaper or magazine devoted to material designed to entertain the general reader, or a feature section) and "stichomythia" (dialogue especially of altercation or dispute delivered in alternating lines, as in classical Greek drama).

While winning words from the early days of the bee were relatively straightforward and not so esoteric, these days contestants must pore over dictionaries and study Latin and Greek roots.

In a post for the OxfordWords blog, Simon Horobin, an English professor at the University of Oxford, wrote of the contrast:

"In addition to their relative orthographic simplicity, these words also differ from more recent winning words in being ones that competitors are likely to have heard of and be able to spell without special study.

None of the recent winning words could be considered common, all are derived from foreign languages and belong to specialized and technical registers."

But this all a good thing because it just means the contestants are getting smarter.

"The spellers themselves are becoming more talented and more knowledgeable about the words," said Valerie Miller, a spokesperson for the Scripps National Spelling Bee. "As they elevate their game, we have to elevate our game as well."

Here's a look back at how the winning words at the spelling bee have evolved. See the full list online.

A new spelling bee champ will be crowned Thursday night. (Follow along, word by word, on Twitter.)
