...the category wasn't levidromes. Jeopardy! had their Teen Tournament games between November 7 and November 20, 2018. In their 10th game of the competition, Jeopardy! had a category called "Forwards and Backwards" in their double jeopardy round. In this category, they would show the answer and then ask for a pair of words for the question.
Alex Trebek, the host for Jeopardy! described the "Forwards & Backwards" category as "We'll need 2 words for each response, and each one will be the reverse of the other".
Since there isn't a formal definition for "Forwards & Backwards" words, Jeopardy! opted with just calling the category "Forwards & Backwards".
This was a classic levidrome category.
In case you missed it, here is an excerpt from the "Forwards & Backwards" round:
We think it is time for Jeopardy! to start using the word levidromes. After all, there is a word for these backwards type of words.
We did a bit of digging. Jeopardy! is in its 35th season. Congratulations Jeopardy! Jeopardy! had made use of the levidromic categories in the past including a few variations. You can view these results in the links below:
I suppose we can let it slip for the older shows because levidrome wasn't even a word yet. (Heck, Levi was not even born yet for most of the episodes). But anything going forward, it should be levidromes.
