New Words in English: How Language Evolves and New Words Enter the Dictionary

English Keeps Moving

English changes because English speakers keep finding new things to talk about. A new device appears, a social habit spreads, a scientific idea becomes public, or a joke catches on online—and sooner or later, people need words for it. Some of those words last. Others burn brightly for a season and disappear.

That constant motion helps explain why the story of English is so absorbing. Modern English would sound strange to Shakespeare, and Shakespeare's English would have sounded different again from Chaucer's. Vocabulary, spelling, pronunciation, and meaning all shift over time.

Large dictionary publishers add hundreds, and sometimes thousands, of entries in a year. Merriam-Webster, Oxford, and other dictionary makers often publicize new batches of words, which can spark arguments as well as curiosity. So where do new English words come from, and how does one move from casual use into a dictionary entry?

Ways English Builds New Words

English gains vocabulary through several familiar patterns of word building.

Adding Prefixes and Suffixes

One of the easiest ways to make a new word is to attach a prefix or suffix to a word that already exists. The prefix "cyber-" appears in terms such as cyberattack, cybersecurity, and cyberbullying. The suffix "-ize" can turn nouns and adjectives into verbs, as in monetize, prioritize, and incentivize.

Putting Words Together

A compound word forms when two existing words combine and create a more specific meaning. Modern examples include "livestream" from live and stream, "fact-check" from fact and check, "crowdfunding" from crowd and funding, and "binge-watch" from binge and watch.

Word Blends and Portmanteaus

Portmanteau words are made by merging pieces of two words. Examples include "brunch" from breakfast and lunch, "smog" from smoke and fog, "podcast" from iPod and broadcast, "blog" from web and log, "mansplain" from man and explain, and "staycation" from stay and vacation.

Short Forms, Initialisms, and Acronyms

Long expressions often get shortened, and some shortened forms begin to function as ordinary words. "Laser" comes from light amplification by stimulated emission of radiation, "scuba" from self-contained underwater breathing apparatus, and "radar" from radio detection and ranging. A newer example is "FOMO," from fear of missing out, which dictionaries now treat as a standard word.

Changing a Word's Grammatical Job

English easily moves a word from one part of speech to another without changing its form. "Google" started as a proper noun, the name of a company, and then became a verb meaning to search online. "Friend" can be used as a verb in social media contexts, as in adding someone to a network. "Adulting" treats "adult" as a verb and then adds "-ing."

Taking Words from Other Languages

English has never been shy about borrowing, and that habit continues. Recent borrowings include "umami" from Japanese for a savory taste, "emoji" from Japanese, "hygge" from Danish for cozy contentment, and "schadenfreude" from German for pleasure in someone else's misfortune.

Creating Words by Trimming Them Back

Back-formation happens when speakers remove a piece that looks like an affix and create a shorter word. "Edit" was formed from "editor," "babysit" from "babysitter," "televise" from "television," and "enthuse" from "enthusiasm."

Words That Echo Sounds

Some words are built to resemble the noises they name. This is onomatopoeia. Words such as "click," "buzz," "ping," "vroom," and "zap" came into English because their sound helps suggest their meaning.

What Gets a Word into a Dictionary

A word can be popular in a friend group, a workplace, or one corner of the internet without qualifying for dictionary treatment. Major dictionary publishers rely on evidence, not personal taste, when deciding what to include.

Lexicographers usually look for three things:

1. Widespread use: The word needs to appear among many speakers or writers, not only within a tiny circle.
2. Sustained use: The word should keep appearing over time rather than vanish after a short-lived trend.
3. Meaningful use: The word must carry a clear enough meaning for editors to define it.

The evidence comes from large text corpora: huge collections of language gathered from books, newspapers, websites, social media, and transcribed speech. Dictionary editors study these databases to see where a word appears, how often it appears, and whether its meaning stays consistent across settings.

Tech as a Word Factory

Technology has supplied English with a steady stream of new vocabulary for decades. Digital life created objects, actions, and habits that earlier speakers did not need to name.

• Computing: algorithm, blockchain, cloud (computing), cryptocurrency, deepfake, machine learning
• Digital culture: FOMO, binge-watch, ghosting, livestream, podcast, unboxing, vlog
• Mobile technology: app, emoji, screenshot, smartphone, swipe, texting
• Internet and social media: blog, doomscroll, hashtag, influencer, meme, selfie, troll, tweet, unfriend, viral

Social Change and Culture

Cultural change also creates vocabulary. As people name new social patterns, public concerns, identities, and shared experiences, new terms spread:

• Environment: carbon footprint, climate anxiety, greenwashing, rewilding, sustainability
• Social awareness: cancel culture, gaslighting, intersectionality, microaggression, woke
• Health and wellness: anti-vaxxer, gluten-free, mindfulness, plant-based, self-care
• Work culture: gig economy, hustle culture, quiet quitting, remote work, work-life balance

Imports from Other Languages

English still follows its long pattern of adopting words from other languages. Global media, travel, food culture, music, and online communication all put English speakers in contact with terms from around the world. Recent and notable borrowings include Japanese words such as tsunami, karaoke, and emoji; Korean terms such as K-pop and mukbang; and many words from other languages.

Recent Dictionary Arrivals

The following entries, added to major English dictionaries in recent years, show how wide the range of new vocabulary can be:

• Rizz: Charm or skill in attracting a romantic partner; a slang term
• Shrinkflation: The practice of making a product smaller while keeping its price the same
• Long COVID: Ongoing symptoms after a COVID-19 infection
• Deepfake: Fake audio or video generated by AI and made to seem real
• Nepo baby: Someone whose career advantage is linked to having famous parents
• Metaverse: A virtual reality environment where users interact with a computer-generated space
• Doomscrolling: The habit of compulsively scrolling through negative news on social media

Old Words, New Senses

Not all vocabulary change involves brand-new forms. Often, an existing word picks up an additional meaning. This process, called semantic shift, has always been part of the development of English:

• "Mouse" now names a computer device as well as a small animal.
• "Viral" moved beyond medicine to describe content shared widely online.
• "Cloud" added a computing meaning in phrases such as cloud storage and cloud computing.
• "Friend" became a verb for adding someone to a social network.
• "Troll" developed the sense of provoking people deliberately on the internet.
• "Stream" can mean sending or receiving audio or video content in real time.

Learning how word meanings shift makes the workings of language much easier to see.

Why Some People Push Back

New words often annoy people. Some sound unnecessary, awkward, or like evidence that the language is getting worse. That reaction is nothing new. In the 16th century, some scholars criticized Latin borrowings as showy "inkhorn terms." In the 18th century, Jonathan Swift objected to shortened forms such as "mob," from mobile vulgus. Modern complaints may target words like "adulting," "selfie," or "mansplain."

Linguists usually describe language as it is used rather than prescribe how people should use it. If a word is widely used, has a recognizable meaning, and fills a communicative role, it belongs to the language whether or not everyone likes it. Change is normal, and it often gives English more precision and range.

Where English Vocabulary Goes Next

English will keep adding words and new meanings. Scientific discovery, global communication, cultural change, and technology will continue to create things that need names. AI, biotechnology, space exploration, and virtual reality are likely to produce especially active areas of vocabulary growth in the decades ahead.

The worldwide use of English also means that words from many varieties of English will have a growing influence on the language's central vocabulary. English has long absorbed, reshaped, and reused words from many sources. That flexibility is one reason it keeps expanding.
