English abbreviations: 100 you'll actually see

Who it's for

For English learners who understand everyday sentences but still pause at IYKYK, LGTM, OOO, or RNG. The set is English-to-English, so it works best from roughly A2–B1: you see the abbreviation, recall the full phrase, and learn how it behaves in a real message. It also makes a quick reference for anyone joining an English-speaking team, forum, or gaming group.

What's inside

Exactly 100 abbreviations chosen for current usefulness across five places where short forms do real work:

• everyday texts and DMs, from BRB and LMK to WDYT;
• social posts and memes, including FYP, GRWM, IYKYK, and POV;
• work chat and email, such as EOD, LGTM, OOO, and WIP;
• forums and community posts, including AMA, AITA, ELI5, and TLDR;
• games, from AFK and GG to DPS, PvP, and RNG.

Every card gives the full English meaning and a natural example containing the abbreviation. A short note appears only when context matters: OP can mean “original poster” or “overpowered,” FPS can be a genre or a performance metric, and a few common expressions are vulgar. There is no IPA because these forms are primarily written; the examples teach where you will actually see them.

How to study

Start with the everyday messages at the top and study for 10–15 minutes at a time. Before revealing a card, expand the letters aloud, then reread the example as one complete message. Notice the same forms in your own chats and feeds; real encounters will make them stick faster than memorizing a bare list. Once the 100 abbreviations feel automatic, keep learning from context: look up unfamiliar forms when they recur instead of trying to memorize every piece of internet shorthand at once.
