Never ones to perendinate, Wayne State University’s Word Warriors are kicking off 2020 by releasing their list of long-lost words to bring back in the coming year. Far from a bunch of mullock, these are beautiful words that have sadly fallen out of use over the years, but Word Warriors are confident their luculent definitions and examples will make logophiles rejoice — and, perhaps, cachinnate.

Now beginning its 11th year, Wayne State’s Word Warriors series promotes words especially worthy of retrieval from the linguistic cellar. Its extensive list is composed of submissions from both administrators of the website as well as the public; participants worldwide have seen their favorite words brought back from the brink of obsolescence at wordwarriors.wayne.edu. New entries are posted there — as well as on Facebook — weekly.

“Each year, I’m curious to see how many old words — which are often new to me — will be recommended to us by our Word Warriors around the globe,” said Chris Williams, assistant director of editorial services in Wayne State’s Office of Marketing and Communications, and head of the Word Warriors program. “Once again, they did not disappoint. The English language is so versatile and unique, and we’ve ended up with a list of 10 great words.”

And now, the Word Warriors’ 2020 list of eminently useful words that should be brought back to enrich our language:
