Textbook French gets you to the café; argot gets you the conversation at the next table. Here’s the everyday slang you’ll hear within five minutes in France — and the register rules that keep it safe.
The quick version — the full lesson is below. More shorts →
Verlan flips syllables (l’envers → verlan). Some flips are now standard casual French:
All of the above is fine with friends and unthinkable in a cover letter. In a shop or with your boss, stay neutral: travail not boulot, manger not bouffer. And swear words — even ones you hear constantly — carry far more weight from a foreign accent. When in doubt, smile and stay textbook.
Open any French group chat and the texting language looks like an encryption exercise. It isn’t — French texting slang follows two simple habits: drop the vowels, and spell sounds with single letters. Here is the list of french text abbreviations that carry 90% of the world of french sms traffic, the text slang terms a french friend will genuinely send you:
How native french speakers actually use this: to save time, yes, but mostly to set a register — texting in french with full spelling reads as formal, even cold, between friends. The same message travels via text as « slt cv? on se voit 2m1? » and by email as full sentences. French internet slang adds a layer on top (verlan like « wesh », English loans like « lol » — yes, used in french alongside mdr), and french pronunciation is the decoder key: read any mystery abbreviation ALOUD and the sound usually reveals the word — that’s the trick every guide to french text lingo forgets to teach, and the reason this free french lesson makes you read the list out loud. Use french abbreviations sparingly at first — receiving them is the skill; sending them fluently comes with common french internet exposure, one text message at a time.
« Mort de rire » — dying of laughter, the French text message abbreviations equivalent of lol/rofl. Escalate with ptdr or the imported lol, both everyday french in chats.
Two rules: strip vowels (salut → slt, beaucoup → bcp) and use letter sounds (c’est → c, j’ai → g). Read any French text slang aloud and the pronunciation gives the word back.
With friends, the opposite — full spelling can read as distant. With strangers, elders or anything professional, write in full: french slang words in the wrong register are the actual rudeness.
No — argot is spoken; text-speak (slt, mdr, jsp) is written. That system has its own lesson: French text speak.
Not offended — sometimes amused. Used naturally and in the right company it earns instant warmth. Match the register of the person talking to you, and keep tu vs vous in mind: slang lives on the tu side.
Films and series are the best register lab: see learn French with films. And beware lookalikes that aren’t slang at all: false friends.
