Misinformation, as opposed to disinformation, was chosen Monday as Dictionary.com's word of the year on the tattered coattails of “toxic,” picked earlier this month for the same honor by Oxford Dictionaries in these tumultuous times.

Jane Solomon, a linguist-in-residence at Dictionary, said in a recent interview that her site's choice of “mis” over “dis” was deliberate, intended to serve as a “call to action” to be vigilant in the battle against fake news, flat earthers and anti-vaxxers, among other conduits.

It's the idea of intent, whether to inadvertently mislead or to do it on purpose, that the Oakland, California-based company wanted to highlight. The company decided it would go high when others have spent much of 2018 going low.

“The rampant spread of misinformation is really providing new challenges for navigating life in 2018,” Solomon told The Associated Press ahead of the word of the year announcement. “Misinformation has been around for a long time, but over the last decade or so the rise of social media has really, really changed how information is shared. We believe that understanding the concept of misinformation is vital to identifying misinformation as we encounter it in the wild, and that could ultimately help curb its impact.”

In studying lookups on the site that trended this year, Dictionary noticed “our relationship with truth is something that came up again and again,” she said.

For example, the word “mainstream” popped up a lot, spiking in January as the term “mainstream media,” or MSM, grew to gargantuan proportions, wielded as an insult by some on the political right. Other words swirling around the same problem included a lookup surge in February for “white lie” after Hope Hicks, then White House communications director, admitted to telling a few for President Donald Trump.

Misinformation, Solomon said, “frames what we've all been through in the last 12 months.” In that vein, the site with 90 million monthly users has busied itself adding new word entries for “filter bubble,” ″fake news,” ″post-fact,” ″post-truth” and “homophily,” among others. Other word entries on the site have been freshened to reflect timely new meanings, including “echo chamber.”

The company's runners-up for the top honor include “representation,” driven by the popularity of the movies “Black Panther” and “Crazy Rich Asians,” along with wins during the U.S. midterm elections for Muslim women, Native Americans and LGBTQ candidates.

But the rise of misinformation, Solomon said, stretches well beyond U.S. borders and Facebook's role in disseminating fake news and propaganda in the Cambridge Analytica scandal. The use of Facebook and other social media to incite violence and conflict was documented around the globe in 2018, she said.
