The same idea can be said four ways in French, from slang to elegant literary style. This page maps the registers, decodes the slang, and explains the rare literary tenses you'll meet in books.
By the end of this unit you can: switch effortlessly between registers.
1Du soutenu à l'argot: Move one idea up and down the four registers of French.
2Le subjonctif littéraire: Recognise the imperfect and pluperfect subjunctive in literary texts.
3Inversion et négation littéraire: Read and use formal inversion, ne… point and the ne explétif.
4De la lettre au texto: Write a formal French letter and decode a text message.
5Fatou change de registre: Tell the same story in three registers in one day.
Grammar and usage, explained
Four floors of the same building
French has a clear register ladder. Soutenu is for speeches, literature and formal letters. Courant is neutral, good for almost anything. Familier is relaxed speech with friends and family. Argotique (slang) belongs to particular groups and changes fast. Native speakers slide between floors all day; at C2 you need to pick the right one deliberately, and to know when a word you heard on the street would sound strange in an email.
Je dois me rendre à mon lieu de travail.I must go to my place of work. (soutenu)
Je dois aller au travail.I have to go to work. (courant)
Faut que j'aille au boulot.Gotta go to work. (familier)
Faut que je file au taf.Gotta head to work. (argot)
Verlan: slang in reverse
Verlan flips the syllables of a word, and often trims or reshapes the vowels. It started as a code in working-class neighbourhoods and some words are now ordinary familiar French. Words can even be re-verlanised: arabe → beur → rebeu. Recognise them; use them only if you're sure of your audience.
C'est chelou, ce truc.That thing is weird. (louche → chelou)
Il est relou, lui.He's so annoying. (lourd → relou)
C'est un truc de ouf !That's insane! (fou → ouf)
Recognise first, produce rarely
Classic novels follow a strict rule: after a past main verb, the subjunctive goes into the past too. Modern French simply uses the present subjunctive instead. You will meet these forms in Hugo, Flaubert, Senghor or Camara Laye, in legal prose and in very formal speeches. Learn to recognise them; only a few frozen phrases are used actively today.
Il fallait qu'elle vienne. (moderne)She had to come.
Il fallait qu'elle vînt. (littéraire)She had to come.
The pluperfect subjunctive: two jobs
Qu'il eût fait is the past of qu'il fît. But it has a second job: in elegant prose it can replace the past conditional. Il eût fallu means exactly il aurait fallu. This is sometimes called the « conditionnel passé deuxième forme ».
On eût dit un prince.You'd have thought he was a prince.
Elle eût préféré se taire.She would have preferred to keep quiet.
When ne travels without pas
In formal French, ne sometimes appears alone. With savoir, pouvoir, oser and cesser it is still negative (je ne saurais dire = I couldn't say). In ne… point it's simply an older, stronger negative. You will see both in literature, in sermons and in jokey imitations of old-fashioned speech.
Je ne saurais vous répondre.I couldn't possibly answer you.
Il ne cesse de se plaindre.He never stops complaining.
Va, je ne te hais point.Go, I do not hate you. (Corneille, Le Cid)
The ne explétif: a ne that means nothing
After avant que, à moins que, de peur que, craindre que, empêcher que and comparisons (plus… que), careful French often adds ne. It does not make the sentence negative. Leave it out in speech if you like; add it in formal writing. To make the clause truly negative you still need pas.
Partons avant qu'il ne soit trop tard.Let's go before it's too late.
C'est plus difficile que je ne pensais.It's harder than I thought.
Adverb first, verb and subject swapped
When à peine, peut-être, aussi (« therefore »), sans doute, encore or ainsi open a sentence, formal French inverts the subject and verb, just as in a question. With a noun subject, keep the noun and add a pronoun: Peut-être le ministre viendra-t-il.
Sans doute a-t-elle raison.She's probably right.
Ainsi s'achève notre voyage.Thus ends our journey.
The formal letter: a ritual
French formal letters (to a ministry, a court, a landlord) follow a fixed ritual. Open with the title alone (Madame, / Monsieur le Directeur,), never a name. State your reason in the first line. Close with a long formula that repeats your opening title. Work emails are lighter (Bonjour Madame Diop, … Cordialement), but the letter still rules in administration, from Paris to Dakar.
Monsieur le Directeur,Dear Sir, (to a director)
Dans l'attente de votre réponse, …Looking forward to your reply, …
Texting: write it as you say it
French texting squeezes spoken French: initials (mdr, jsp, tkt), sounds (c = c'est, g = j'ai, koi = quoi), and dropped ne. It's all familiar register. Never let it leak into a work email, but do learn to read it: your friends and colleagues will text you this way.
tkt g fini, c bondon't worry, I've finished, it's fine
dsl jsp si je peux venirsorry, dunno if I can come
Scene: one day, three registers

Le subjonctif littéraire
Listen
French
English
qu'il fût
that he was / be (imperfect subjunctive of être)Watch the circumflex: il fut (no accent) is the passé simple; qu'il fût is the subjunctive.
qu'il eût
that he had (imperfect subjunctive of avoir)Il eut (passé simple) and qu'il eût sound the same. Only the circumflex tells them apart.
qu'elle vînt
that she came (imperfect subjunctive of venir)Today's spoken French says qu'elle vienne.
qu'il parlât
that he spoke (imperfect subjunctive of parler)Third person singular: take the passé simple, put a circumflex on its last vowel and end it in t. Il parla → qu'il parlât; il finit → qu'il finît; il vint → qu'il vînt.
qu'il eût fait
that he had done (pluperfect subjunctive)Qu'il eût or qu'il fût + past participle. In everyday French: qu'il ait fait.
il eût falluIl eût fallu partir plus tôt.(We ought to have left earlier.)
it would have been necessaryA literary way of saying il aurait fallu.
ne fût-ce quePassez nous voir, ne fût-ce qu'une heure.(Come and see us, if only for an hour.)
if only, even if onlyA fixed formal phrase still used today. The everyday version is ne serait-ce que.
dussé-jeJe finirai ce roman, dussé-je y passer la nuit.(I'll finish this novel even if it takes me all night.)
even if I had toFrom devoir. The final e becomes é before the inverted je. Very literary.
Inversion et négation littéraire
Listen
French
English
ne… point
not (at all), literaryAn old-fashioned, emphatic ne… pas. Common in classic literature and in jokey imitations of it.
je ne saurais…
I couldn't possibly…With savoir, pouvoir, oser and cesser, formal French can drop pas: je ne saurais dire, je n'ose le croire, il ne cesse de pleuvoir.
avant qu'il ne parte
before he leavesThis ne is the ne explétif: it is NOT negative. It's optional and marks a careful, formal style.
je crains qu'il ne pleuve
I'm afraid it may rainAfter verbs of fearing, formal French adds a ne explétif. The real negative needs pas: je crains qu'il ne pleuve pas.
à peine… queÀ peine était-elle sortie que la pluie se mit à tomber.(No sooner had she gone out than it began to rain.)
no sooner… than, hardly… whenAt the start of a sentence, à peine triggers inversion.
peut-être viendra-t-il
perhaps he'll comeFormal: peut-être at the start + inversion. Everyday: peut-être qu'il viendra, or il viendra peut-être.
aussi a-t-il…
and so he…, therefore he…False friend! At the start of a clause, aussi + inversion means « therefore », not « also ».
encore faut-il…C'est une bonne idée. Encore faut-il la financer.(It's a good idea. Still, it has to be funded.)
still, one has to…, that's assuming…
