'Vaccine' is Merriam-Webster's 2021 word of the year

With an expanded definition to reflect the times, Merriam-Webster has declared an omnipresent truth as its 2021 word of the year: "vaccine."

"This was a word that was extremely high in our data every single day in 2021," Peter Sokolowski, the dictionary's editor-at-large, told The Associated Press ahead of Monday's announcement.

"It really represents two different stories. One is the science story, which is this remarkable speed with which the vaccines were developed. But there's also the debates regarding policy, politics and political affiliation. It's one word that carries these two huge stories."

The Oxford English Dictionary earlier chose"vax" as its word of the year.

Last year,Merriam-Webster chose "pandemic."

"The pandemic was the gun going off, and now we have the aftereffects," Sokolowski said.

An old word with modern meaning

At Merriam-Webster, searches for "vaccine" increased 601 per centover 2020, when the first U.S. shot was administered in New York in December after quick developmentand months of speculation and discussion over efficacy.

The world's first jab had occurred earlier that month in the U.K.

Compared to 2019, when there was little urgency or chatter about vaccines, Merriam-Webster logged an increase of 1,048 per centin searches for the wordthis year.

Debates over inequitable distribution, vaccine mandates and boosters kept interest high, Sokolowski said. So did vaccine hesitancy and friction over vaccine passports.

The word "vaccine" wasn't birthed in a dayor due to a single pandemic. The first known use stretches back to 1882, but references pop up earlier related to fluid from cowpox pustules used in inoculations, Sokolowski said.

It was borrowed from the New Latin "vaccina," which goes back to Latin's feminine "vaccinus," meaning "of or from a cow." The Latin for cow is "vacca," a word that might be akin to the Sanskrit "vasa," according to Merriam-Webster.

Inoculation, on the other hand, dates to 1714, in one sense referring to the act of injecting an "inoculum."

Earlier this year, Merriam-Webster added to its online entry for "vaccine" to cover all the talk of mRNA vaccines, known asmessenger vaccines, such as those for COVID-19 developed by Pfizer-BioNTech and Moderna.

While other dictionary companies choose words of the year by committee, Merriam-Webster bases its selection on search data, paying close attention to spikes and, more recently, year-over-year increases in searches after weeding out evergreens. The company has been declaring a word of the year since 2008.

Word of the year runners-up

Among its runners-up in the word biography of 2021:

INSURRECTION: Interest was driven by the deadly Jan. 6 riot at the U.S. Capitol. Arrests related to the riot continue, as do congressional hearings over the attack carried out by supporters of former U.S. president Donald Trump.

Searches for the word increased by 61,000 per cent over 2020, Sokolowksi said.

INFRASTRUCTURE: U.S.President Joe Biden signed abipartisan infrastructure billinto lawearlier this month. When Biden proposed help with broadband access, elder care and preschool, conversation changed from not only roads and bridges but "figurative infrastructure," Sokolowski said.

"Many people asked, what is infrastructure if it's not made out of steel or concrete? 'Infrastructure,' in Latin, means underneath the structure," he said.

PERSEVERANCE: It's the name of NASA's latest Mars rover. It landed Feb. 18, 2021. "Perseverance is the most sophisticated rover NASA has ever sent to the Red Planet, with a name that embodies NASA's passion, and our nation's capability, to take on and overcome challenges," the space agency said.

The name was thought up by Alexander Mather, a 14-year-old seventh-grader at Lake Braddock Secondary School in Burke, Va. He participated in an essay contest organized by NASA. He was one of 28,000 K-12 students to submit entries.

NOMAD: The word had its moment with the 2020 release of the film Nomadland.It went on to win three Oscars in April 2021, including best picture, director (ChloZhao) and actress (Frances McDormand). Zhao became the first woman of colour to win best director.

The AP's film writer, Jake Coyle, called the indie success "a plain-spoken meditation on solitude, grief and grit."He wrote that it "struck a chord in a pandemic-ravaged year. It made for an unlikely Oscar champ: A film about people who gravitate to the margins took centre stage."
