100+ Internet Abbreviations for Texting and Tweeting (2026 List)

The lists are ordered by where you are most likely to see the abbreviation. Each row gives the abbreviation, its meaning, an example message, and how it is said out loud: as letters (O-M-G, stress on the last one), as a word (FOMO, GOAT), both (ASAP is /ˌeɪ.es.eɪˈpiː/ and /ˈeɪ.sæp/), or written only (nobody says “I-C-Y-M-I”).

Where a dictionary records a pronunciation, the table follows it: Cambridge lists OMG only as letters, ASAP both ways, and LOL as /lɑːl/ and /ˌel.oʊˈel/. Where usage is mixed, the row says so. Letter names and their stress are what learners most often get wrong; the pronunciation practice guide covers them.

Work chat and email abbreviations (24)

The smallest set and the most useful one for a non-native professional: these 24 cover Slack, Teams, email and calendar invites. Most are said as letters, so they are easy to use in a meeting.

Two of these carry tone. ASAP from a manager reads as a deadline, so many teams write “by Thursday” instead. TL;DR at the top of your own message is polite; as a reply to someone else’s it says “I did not read this”. The business English conversation guide covers the spoken side of the same updates.

Texting abbreviations for group chats with friends (25)

Group chats produce the most abbreviations and the fewest spoken ones: IDK, TBH and OMG are said as letters; almost everything else is typed only.

Lowercase is the norm here: “LOL” and “IDK” in capitals look formal or angry. The greetings that open these chats (hey, sup, yo) are in the guide to English greetings.

Social media and comment-section abbreviations (17)

Comment sections on TikTok, Instagram, X and Reddit have their own set; several are said as words (FOMO, GOAT, YOLO).

W and L come from sports scores. Wiktionary records W as an internet-slang abbreviation of “win” with L as its opposite. NSFW is a label, not an insult: it marks a link, and typing it is polite.

Gaming, dating and marketplace abbreviations (11)

Gaming abbreviations are often spoken over voice chat; marketplace ones live in listings and are never said.

Numbers, symbols and tone tags (10)

The oldest texting shorthand replaces syllables with digits, from the days of 160-character SMS; the newest adds a tone tag after a sentence. None are spoken: you read the word they stand for.

The emoticon meanings follow Wikipedia’s list of emoticons, which gives “:/” as skeptical, annoyed, undecided or hesitant. Tone tags such as /s grew out of the older “/sarcasm” written like an HTML closing tag, according to the Wikipedia article on tone indicators. They matter because sarcasm does not survive text, and a missing /s starts arguments.

Rude abbreviations for texting: recognize them, do not send them (14)

These carry a swear word inside the letters. Reading them tells you the sender is angry, joking hard, or both; typing them to anyone outside close friends is a mistake.

AF is the one that crosses over: the Cambridge Dictionary lists AF as a written abbreviation used on social media for emphasis, and brands use it in captions. It is still off-limits in a work message. SMH is not rude, only dismissive, which is why it sits in the friends table.

Which texting abbreviations are safe at work

An abbreviation is safe at work when the reader cannot read it as impatience or mockery. That single test sorts the list into three groups and explains why the same letters can be fine from a peer and wrong from a manager: ASAP from above is a deadline, not a request.

Saying work abbreviations out loud: a Slack thread read to a colleague

Reading a thread aloud is a real work task: you summarize a channel for someone who missed it or read a message during a call. This one packs the spoken abbreviations into 8 sentences. Listen once, then record yourself.

• Listen for: the stress on the last letter of each abbreviation (F-Y-I, E-T-A, E-O-D, P-T-O), and ASAP said either way.
• Watch: N/A is two letters, “N-A”; OOO is three separate O’s, and many speakers simply say “out of office”.
• Make it yours: read the same thread with your own project, names and dates.

What to say when you do not know an abbreviation

Asking is normal; native speakers do it constantly, because every team invents its own. Priya below asks with a guess attached, which gets a yes-or-no answer instead of a lecture.

• In a chat: “Sorry, what does OOO mean?” or “Quick one: what’s COB here, 5 or 6?”
• In a meeting: “When you say E-O-W, do you mean this Friday?” Repeat the letters, then your guess.
• To buy time: “Got it, I’ll check and get back to you.” Then search the abbreviation plus “meaning”.

New text abbreviations in 2026: where they come from and how to check one

New abbreviations come from platforms, games and sounds; dictionaries catch up years later. Dictionary.com’s word of the year for 2025 was “67”, a number from a song that spread through TikTok videos and, by the site’s own account, has no fixed meaning: it can mean “so-so”, work as a catch-all reply, or just signal that the writer is in on the joke.

The older ones on this page are already settled. The Cambridge Dictionary has entries for IYKYK, NGL, ICYMI and TLDR, each labeled a written abbreviation used on social media and in text messages.

• Check a dictionary first. If Cambridge or Merriam-Webster has an entry, the meaning is settled.
• Then Wiktionary. Its appendix of English internet slang lists hundreds with short glosses and notes when a form has two readings, such as gtg for “got to go” and “good to go”.
• Treat Urban Dictionary as a signal, not a source. Anyone can post a definition; it shows an abbreviation exists, not what it means in your chat.
• Search the abbreviation with the platform name. “fyp meaning tiktok” finds the right sense, because many differ between Reddit, games and work (OP, GG, POC).
