Dictionary.com Adds Coronavirus Words To The Dictionary

Normally, we track new words for years before seeing enough evidence to convince us they have the staying power to merit inclusion in our traditional dictionary.

Well, it’s not a normal day at the office. We’re all working at home, for one thing.

COVID-19 has changed the dictionary world as suddenly and profoundly as it has changed all of our personal and professional lives. In a period of just a few weeks, we’ve acquired a new vocabulary to talk about novel coronavirus.

And so our lexicographers have updated Dictionary.com with some of these new coronavirus words and senses to help you stay informed and safe during these unprecedented times. Find the complete list at the end of the article.

One word has made an immeasurable impact on our lives and language. Find out what the 2020 Word of the Year is here.

New coronavirus words for public health

Traditionally, there are subject-specific dictionaries, like medical dictionaries, for those words that only professionals in the field would know and use. Suddenly, however, everyday people know and use words like asymptomatic and prodrome, or “an early symptom that signals the onset of an illness or disease.” Amid the pandemic, we’re all speaking like epidemiologists.

We’re now familiar with specialized lingo, including abbreviations like PPE (personal protective equipment). You might read an article in your local paper about the gym or the grocery store that educates you about fomites or a sneeze’s viral load. Words that we might have known primarily from other contexts, like corona or novel, now have newly significant meanings, so we also revised existing entries to add definitions for these specific scientific senses.

New coronavirus words in society and the economy

Social behaviors and government guidance are also common topics of conversation. We’ve added noun and verb definitions to social distance, a word with a long history in the field of sociology, whose public health meanings appeared among specialists in that field less than 20 years ago. But today, at the forefront of our minds are newer definitions of the term, especially “to maintain a safe or appropriate distance from other people, especially to slow the spread of a contagious illness or disease.”

Shelter in place is not a new designation (it dates back 40 years), but it has a specific meaning, unlike the more general expression hunker down. And while containment has many meanings, we’ve updated the one that applies to public health and safety.

Social distancing and shelter-in-place guidelines have, of course, caused society—and the economy—great strain, too. Hard times put grim and disheartening stories into the headlines, so our lexicographers have been evaluating and updating definitions for words like profiteering, price gouging, and gouge.

We can still have fun

Humanity also appears to be hard-wired to take the building blocks for communication and use them for fun, whether with puns and double entendres, or tongue twisters and silly noises. Social media is ripe for this kind of language play, as you see with riffs on memes and phrasal templates designed to be manipulated for humor—if often gallows humor, in the case of the coronavirus crisis.

So, it was only a matter of time before COVID-19 became rona online. The rona and other short variants began showing up in irreverent or funny comments by mid-March, just as the grim realities of the pandemic were becoming clear.

Curious about more slang terms that have sprung up amid the coronavirus? We’ve been tracking them here.

Language in the time of COVID-19

Linguists will tell you that it’s not unusual for language to become highly productive and innovative in times of upheaval and tragedy. But why?

War, slavery, economic collapse, and mass migration have historically jolted people into unforeseen contact that changes their language. Not dissimilarly, the COVID-19 pandemic has thrust us out of our regular linguistic bubbles and brought us into contact with specialized vocabulary we couldn’t have predicted needing.

The virus has abruptly upended life for many. In response, we see people doing what human beings have always done—acquiring and inventing new words to understand and to exercise control over the world. The team at Dictionary.com will be here alongside you, continuing to document, explain, and share the words that are helping us make sense of our new reality.
