Overview
In 2021, Oxford Languages selected 'vax' as its Word of the Year, marking a pivotal moment in how major dictionaries recognize linguistic change. The term, a colloquialism for vaccine or vaccination as a noun and vaccinate as a verb, had been relatively rare in English language corpora until the pandemic accelerated its adoption. By September 2021, vax appeared over 72 times more frequently than it had the previous year, making it impossible for lexicographers monitoring the English language corpus to ignore. This explosive growth reflected the global conversation surrounding COVID-19 vaccination campaigns and the urgent need for concise terminology to discuss immunization efforts. The selection of vax over other pandemic-related terms demonstrated how Oxford Languages used data-driven methodology to capture the zeitgeist, similar to how other major dictionaries like Dictionary.com and Merriam-Webster track cultural moments through language.
📊 Linguistic Data & Selection
Oxford Languages' lexicographers employed rigorous corpus analysis to justify their selection, examining frequency data and linguistic patterns across their vast database of English usage. The word vaccine itself, already common before 2021, more than doubled in frequency between September 2020 and September 2021, but vax's trajectory was even more dramatic. The selection process went beyond simple frequency counts—the team analyzed how vax generated numerous derivatives and compounds that appeared in informal contexts worldwide, from 'vax sites' and 'vax cards' to phrases like 'getting vaxxed' and 'fully vaxxed.' Oxford Languages published a comprehensive report examining vaccine-related language developments, including neologisms, regional variations, and how the language of vaccines influenced other major languages globally. This evidence-based approach contrasted with previous years when words like 'pandemic' (Merriam-Webster's 2020 selection) had captured attention through massive lookup increases of 5700%, showing how different dictionaries weigh frequency against cultural significance.
💬 Language Evolution & Derivatives
The linguistic ecosystem surrounding vax demonstrated how rapidly language adapts to urgent social needs, much like how artificial intelligence terminology evolved with ChatGPT's emergence. Beyond the base word, vax spawned creative compounds and phrases that permeated everyday communication: 'vaxxed,' 'double-vaxxed,' 'unvaxxed,' and 'vax hesitancy' became standard vocabulary in news media, social conversations, and policy discussions. The phrase 'a shot in the arm' experienced renewed usage, with speakers creating prolific punning combinations that blended literal meanings (injection into the arm) with figurative ones (an encouraging stimulus). International variations emerged as well—the report noted how different languages adopted or adapted vaccine-related terminology, reflecting how English linguistic innovations influence global communication patterns. These derivatives and compounds provided what lexicographers called 'a lexical snapshot of the concerns of the year,' capturing not just medical information but also the emotional tenor of 2021's recovery from lockdowns and the shared experiences of vaccination rollouts.
🔮 Legacy & Impact on Lexicography
The selection of vax as Word of the Year 2021 established a precedent for how major dictionaries recognize pandemic-era language, influencing subsequent years' selections across multiple institutions. The Economist, which began publishing its own Word of the Year in 2021, also selected 'vax,' while Dictionary.com chose 'allyship' and Merriam-Webster selected 'perseverance,' each reflecting different aspects of 2021's cultural moment. The vax phenomenon demonstrated that language evolution during global crises follows predictable patterns: urgent need drives rapid adoption, derivatives proliferate, and terms become fully absorbed into everyday speech within months rather than years. Professor Kate Burridge from Monash University noted that while recent years had seen 'dismal, grizzly words' dominate dictionary selections, vax represented a more neutral linguistic marker of the era's defining event. The legacy of this selection continues to influence how lexicographers approach Word of the Year decisions, with subsequent years seeing selections like 'hallucinate' (2023, referencing AI) and 'parasocial' (2025), showing how dictionaries now prioritize capturing technological and social shifts through language rather than solely emphasizing negative events.

Frequently Asked Questions
Why was 'vax' chosen over other pandemic-related words?
Oxford Languages used data-driven corpus analysis showing vax experienced a 72-fold frequency increase by September 2021. While 'vaccine' itself doubled in frequency, vax's explosive growth, combined with its prolific derivatives ('vaxxed,' 'double-vaxxed,' 'vax sites'), made it the most striking linguistic marker of 2021. The term captured both the medical reality and the emotional atmosphere of the year better than alternatives.
Did other dictionaries also select 'vax' as their Word of the Year?
The Economist, which began publishing its Word of the Year in 2021, also selected 'vax.' However, other major dictionaries made different choices: Dictionary.com chose 'allyship,' Merriam-Webster selected 'perseverance,' and Cambridge Dictionary chose 'persist.' Each selection reflected different aspects of 2021's cultural moment and different methodologies for evaluating linguistic significance.
How did Oxford Languages measure the frequency of 'vax'?
Oxford Languages monitored their English language corpus—a large database of real-world English usage—tracking how often 'vax' appeared over time. By comparing September 2021 data to September 2020, they found vax was 72 times more frequent. They also analyzed derivatives and compounds (vaxxed, vax cards, vax sites) appearing in informal contexts across various sources.
Did the selection of 'vax' influence how other languages adopted vaccine vocabulary?
Yes. Oxford Languages' report examined how vaccine-related language developments influenced languages beyond English, looking at selections of the most-spoken languages globally. The prominence of 'vax' in English media and international discourse influenced how other languages either adopted the English term or created their own equivalents, demonstrating how English linguistic innovations spread globally.
What does the selection of 'vax' reveal about how dictionaries choose Words of the Year?
The vax selection demonstrated that modern dictionaries increasingly use evidence-based, data-driven approaches rather than relying solely on editorial judgment. It showed that Word of the Year selections capture how language evolves during major global events, serve as cultural documentation of historical moments, and reflect the urgent communication needs of societies. This approach influenced subsequent years' selections, including AI-related terms like 'hallucinate' (2023).
