In May, the words "hashtag," "selfie" and "tweep" were among 150 new words and definitions added to Merriam-Webster’s Collegiate Dictionary, proof of how our culture continues to expand our communication.

Still, we think some old words deserve a bit more love.

As part of its initiative to draw attention to some of the English language's most expressive — yet regrettably neglected — words, Wayne State University has released its annual list of the year’s top 10 words that deserve to be used more often in conversation and prose.

Now beginning its seventh year, Wayne State’s Word Warriors series promotes words especially worthy of retrieval from the linguistic closet.

The Word Warriors’ extensive list is composed of submissions from both administrators of the website as well as the public; logophiles 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 Twitter and Facebook, each week.

"The English language has more words in its lexicon than any other," says Jerry Herron, dean of WSU's Irvin D. Reid Honors College and a member of the website’s editorial board. "By making use of the repertoire available to us, we expand our ability to communicate clearly and help make our world a more interesting place. Bringing these words back into everyday conversation is just another way of broadening our horizons."

And now, the Word Warriors' 2015 list of eminently useful words that should be brought back to enrich our language:
