Lesson 48: Register, idioms, and the spoken/written divide

Part 1: The three registers — map of the terrain

French marks register more sharply than English. The same idea is expressed three different ways depending on who you're talking to and where.

Register	When	Markers	Example: "work"
soutenu (elevated)	literature, speeches, formal letters, legal writing	inversion, passé simple, imparfait du subjonctif, ne explétif, rare vocabulary	œuvrer, labourer
courant (standard)	press, textbooks, neutral conversation, business email	est-ce que, full forms, ne present in negation	travailler
familier (casual)	friends, family, informal texts	dropped ne, on for nous, syllable reduction, slang	bosser

Below familier sit two further layers:

• argot — slang proper (often crude, sometimes technical to a group: prison argot, school argot, regional argot)
• verlan — syllable-reversed slang from the Paris banlieues, now mainstream (femme → meuf, louche → chelou)

Trap! There is no "neutral" register in the abstract — register is always relative to the situation. Bonjour Monsieur is neutral with a stranger and pointedly formal between close friends.

The four filters that pick your register:

1. Who is speaking to whom (status, age, closeness)
2. Where (café vs. board meeting)
3. Channel (text message vs. paper letter)
4. Topic (joke vs. condolences)

For English speakers: English has register too (kid / child, cops / police officers, guts / courage), but the grammar doesn't change with register. In French, even the syntax shifts — questions are built differently, negation is built differently, subject pronouns are different. That's what makes register feel more "stratified" in French.

Part 2: The grammar of spoken French

Written and spoken French are nearly different systems. The differences below are mandatory if you want to understand a native at full speed and sound natural yourself.

2.1. Dropped ne (callback to Lesson 43)

In speech ne almost always disappears. Only pas, plus, jamais, rien, personne survive.

Written / courant	Spoken / familier
Je ne sais pas.	J'sais pas. / Chais pas.
Il n'y a personne.	Y a personne.
Je n'ai rien fait.	J'ai rien fait.
On ne peut plus.	On peut plus.

Ne disappears in 90%+ of spoken French. But keep it in writing — without it, the text reads like a text message.

2.2. On for nous

In spoken French, nous is nearly dead as a subject pronoun. On has taken over (3rd person singular conjugation, but meaning "we").

Written	Spoken
Nous allons au cinéma.	On va au ciné.
Nous avons mangé.	On a mangé.
Nous sommes prêts.	On est prêts. (agreement by sense!)

Subtlety: in written texts on = "one / people in general". In speech, on almost always means "we". Context disambiguates.

2.3. Questions — three forms, three registers

One question, three shapes.

Register	"Where do you live?"
soutenu (inversion)	Où habites-tu ?
courant (est-ce que)	Où est-ce que tu habites ?
familier (intonation / postposed wh-word)	Tu habites où ?

Register	"What are you doing?"
soutenu	Que fais-tu ?
courant	Qu'est-ce que tu fais ?
familier	Tu fais quoi ?

Remember: inversion sounds stuffy in casual speech. The postposed wh-word (tu habites où ?) is what natives actually say.

2.4. Phonetic reduction

In fast speech, syllables get swallowed. These aren't "mistakes" — they are the norm of spoken French.

Full form	Reduced	Sounds like
je suis	chuis	"shwee"
je ne sais pas	chais pas	"shay-pah"
tu as	t'as	"ta"
tu es	t'es	"teh"
il y a	y a	"ya"
celui-là	çui-là	"swee-lah"
je vais	j'vais / chvais	"zhveh"
qu'est-ce que tu	keskeu / qu'est-c'que tu	"kesk-tu"

Don't write these in normal text. Only in dialogue inside a novel, or in chat messages.

Part 3: Lexical triples — one concept, three registers

This is the heart of register mastery. Learn these in threes.

soutenu	courant	familier	Meaning
s'alimenter	manger	bouffer	to eat
demeurer / résider	habiter	crécher	to live (somewhere)
dérober	voler	piquer / faucher	to steal
se vêtir	s'habiller	se saper	to get dressed
débuter	commencer	s'y mettre	to begin
s'enquérir de	demander	demander	to ask
œuvrer	travailler	bosser	to work
se hâter	se dépêcher	se grouiller	to hurry
appréhender	avoir peur	flipper	to be afraid
congédier	renvoyer	virer	to fire (someone)
ingérer / consommer	boire	picoler	to drink (alcohol)
acquérir	acheter	choper	to buy / get
solliciter	demander	demander	to request
comprendre / saisir	comprendre	piger	to understand
dormir / sommeiller	dormir	pioncer / roupiller	to sleep
importuner / contrarier	ennuyer	embêter / saouler	to annoy / bother
converser / s'entretenir	parler	causer / jaser	to talk
une automobile	une voiture	une bagnole	car
un domicile / une demeure	une maison	une baraque / une crèche	house / home
un emploi	un travail / un boulot	un job / un taf	job
de l'argent / des fonds	de l'argent	du fric / du pognon / du blé / de la thune	money
un repas	un repas	la bouffe	meal / food
un ami	un ami	un pote	friend
agréable	sympathique / agréable	sympa / chouette / cool	nice / pleasant
splendide / magnifique	beau	super / génial / canon	beautiful / great

The mixing rule: stay inside one register per sentence. J'ai mangé une excellente bouffe chez ma grand-mère — lexical car crash. Splendide bagnole ! — same disaster.

English-speaker shortcut: the soutenu column is full of Latin/cognate words English already owns — acquire, solicit, reside, demeanor, dispatch, dispatch, dismiss, ingest, comprehend. When you don't know the elevated French word, try the English Latinate cognate — you'll often be right.

Part 4: Idioms — the must-know minimum

Idioms are your passport into living French. Memorize them whole, don't try to parse them word-by-word.

Idiom	Literal	Meaning
avoir le coup de foudre	to have the lightning strike	to fall in love at first sight
coûter les yeux de la tête	to cost the eyes from the head	to cost a fortune
poser un lapin à qqn	to put down a rabbit for someone	to stand someone up
tomber dans les pommes	to fall into the apples	to faint
avoir un chat dans la gorge	to have a cat in the throat	to be hoarse
donner sa langue au chat	to give one's tongue to the cat	to give up (in a riddle)
être au bout du rouleau	to be at the end of the roll	to be at the end of one's rope
ça ne casse pas trois pattes à un canard	it doesn't break three legs of a duck	nothing to write home about
avoir le cafard	to have the cockroach	to feel blue / down
prendre ses jambes à son cou	to take one's legs around one's neck	to run away
mettre son grain de sel	to put in one's grain of salt	to butt in with an opinion
être dans la lune	to be on the moon	to have one's head in the clouds
raconter des salades	to tell salads	to tell lies / spin yarns
avoir un poil dans la main	to have a hair in the hand	to be lazy
en faire tout un fromage	to make a whole cheese out of it	to make a mountain out of a molehill
il pleut des cordes	it rains ropes	it's pouring (cats and dogs)
avoir le coup de barre	to get hit with the bar	to suddenly feel exhausted
se serrer la ceinture	to tighten the belt	to tighten one's belt (cut spending)
ne pas être dans son assiette	not to be in one's plate	to feel off / under the weather
avoir la pêche / la patate / la frite	to have the peach / potato / fry	to be in great form

Part 5: Argot and verlan — what to recognize, what to use

Argot is its own layer. Recognize it, use it carefully.

Everyday harmless argot (familier)

Word	Meaning
un mec	guy, dude
une meuf	girl, chick (verlan from femme)
un truc	thing, stuff
un machin	thingamajig, whatsit
ouais	yeah (instead of oui)
nan	nope (instead of non)
trop	very, super (c'est trop bien = "it's so good")
grave	seriously, totally (ouais, grave = "yeah, totally")
chelou	shady, weird (verlan from louche)
relou	annoying (verlan from lourd)
un truc de ouf	something insane (ouf = verlan of fou)

Verlan — syllable inversion

Verlan flips a word's syllables. The name itself is verlan: l'envers ("the reverse") → verlan.

• femme → meuf
• louche → chelou
• lourd → relou
• fête → teuf
• bizarre → zarbi
• flic (cop) → keuf
• fou → ouf
• père → reup ; mère → reum

Crude argot — recognize only!

Word	Strength	Translation
putain	basic expletive	"damn" / stronger ("f---")
merde	mild	"crap" / "shit"
con / conne	insulting	"idiot" / "moron" (also a strong vulgarity)
foutre / s'en foutre	vulgar	"to give a damn" / "I don't give a damn"
bordel	mild expletive / noun	"mess" / "what a mess"

Safety rule: in interviews, with bosses, with strangers older than you — never go beyond courant. Hearing putain from a French person is normal. Saying it yourself at the wrong moment costs you face.

Part 6: The written hierarchy

Writing has its own register ladder.

Channel	Register	Markers
Text / chat	familier+	reductions, emoji, coucou, bisous
Email to a friend	familier / courant	Salut, À +, Bises
Email to a colleague	courant	Bonjour, Cordialement
Business letter	soutenu	Madame, Monsieur, Veuillez agréer, Madame, l'expression de mes salutations distinguées
Essay / article	courant → soutenu	no contractions, full negation, little on=nous
Legal text	soutenu	passé simple, subjonctif, nul, aucun

Email politeness formulas — memorize as fixed blocks:

Opening	Closing
Bonjour, (standard)	Cordialement, (standard)
Madame, Monsieur, (formal, name unknown)	Bien cordialement, (warmer)
Cher Monsieur Dupont, (formal, name known)	Sincères salutations,
Coucou ! (to a friend)	Bises / Bisous (close friends)

Trap! Cordialement is the safe default. Amicalement is warmer, for acquaintances. Bises is reserved for close friends. Mixing these up makes you sound either cold or weirdly familiar.

Part 7: Links to earlier lessons (review)

R1 (← Lesson 47): Emphasis and register

Emphasis structures shift by register:

• soutenu: Ce sont les enfants qui ont décidé.
• courant: C'est les enfants qui ont décidé. (grammatically "wrong", but universal in speech)
• familier: Les gosses, ils ont décidé, eux. (triple topic marking)

C'est instead of ce sont is the spoken standard; in strict writing it's still considered a mistake.

R2 (← Lesson 46): Nominalization and register

High density of nominalizations = soutenu. Verbs and full clauses = courant/familier.

soutenu	courant
L'augmentation des prix inquiète la population.	Les prix augmentent et ça inquiète les gens.
La mise en œuvre du projet est imminente.	Le projet va bientôt commencer.
Suite à la réception de votre courrier…	Quand on a reçu votre lettre…

R3 (← Lesson 43): Negation by register

• soutenu: Je ne le sais point. / Nul ne le sait. / Je crains qu'il ne vienne. (ne explétif)
• courant: Je ne le sais pas.
• familier: J'le sais pas. / Chais pas.

Ne … que is register-neutral but slightly literary. Spoken equivalent: seulement / juste.
