There is a reason French sounds like one long word. It is: French does not delimit words in speech. It delimits rhythm groups, and inside a group the consonants and vowels flow across the word boundaries as if the spaces were not there. Il est arrivé en avion comes out as four syllables plus one: i-les-ta-ri-vé-a-na-vion.
Until you know the rules for that flow, two things stay out of reach: hearing where one word ends in fast speech, and reading aloud without sounding like a list. Both are C1 descriptors. This lesson is the system.
A liaison pronounces a normally silent final consonant because the next word begins with a vowel. It is grammatical: it happens inside tight syntactic groups and stops at real boundaries.
| French | Pronunciation | Group |
|---|---|---|
| les amis | lay-zah-MEE | determiner + noun |
| un grand homme | uhn grahn-TOM | adjective + noun |
| nous avons | noo-zah-VOHN | pronoun + verb |
| ils ont | eel-ZOHN | pronoun + verb |
| très intéressant | tray-zan-tay-ray-SAHN | adverb + adjective |
| chez elle | shay-ZEL | preposition + pronoun |
| dix euros | dee-ZUH-roh | numeral + noun |
| quand il arrive | kahn-teel ah-REEV | fixed conjunction |
Note the consonant changes: final s and x liaise as z, d as t, f in neuf as v (neuf heures → neu-VUHR), and a nasal vowel may denasalise (bon ami → bo-nah-MEE).
| Case | Example | Why |
|---|---|---|
| After et | et // un ami | a fixed prohibition |
| Before h aspiré | les // haricots | the h blocks it |
| After a singular noun | un enfant // adorable | major boundary |
| Before oui, onze, huit | les // onze joueurs | protected words |
| Across a comma or a clause break | Il est parti, // au fond | prosodic boundary |
| Inverted subject + vowel | Viennent-ils // à midi ? | after the pronoun group |
Between those two lists lies a large zone where the liaison is a style choice. Making it raises the register; omitting it lowers it.
Je suis allé — je swee-zah-lé (careful) vs je swee a-lé (casual).
Après avoir mangé, pas encore, c’est un peu… — all optional.
Rule of thumb: a news reader makes almost all of them, a politician making a speech makes all of them plus one or two that are not really allowed, and a friend in a café makes very few.
These words begin with a consonant as far as French grammar is concerned: no liaison, no elision, no l’.
| French | Pronunciation | Meaning |
|---|---|---|
| le héros | luh ay-ROH | the hero (but l’héroïne has h muet) |
| les haricots | lay ah-ree-KOH | the beans |
| le hasard | luh ah-ZAR | chance |
| la hauteur | lah oh-TUHR | the height |
| le hall | luh OL | the lobby |
| la honte | lah OHNT | the shame |
| le hibou | luh ee-BOO | the owl |
| la haine | lah EN | hatred |
| le homard | luh o-MAR | the lobster |
| huit | WEET | eight (protected, though not an h aspiré) |
Most French dictionaries print an apostrophe or an asterisk before the entry for an h aspiré word. There is no way to predict it from the spelling, and the list is short enough to learn — perhaps sixty words in common use, of which the ones above cover most of your daily needs.
Liaison resurrects a silent consonant. Enchaînement moves a consonant that was already pronounced onto the next syllable. It happens constantly and is never optional.
une amie → ü-nah-MEE · quelle heure → ke-LUHR · il arrive → i-lah-REEV · cette année → se-tah-NAY
This is the main reason French word boundaries are inaudible. When you cannot find the words in a recording, it is usually enchaînement, not speed.
The unstable e (in le, je, petit, samedi) is dropped whenever the result is comfortably pronounceable, and kept when dropping it would collide three consonants. That is the loi des trois consonnes.
| Written | Said | Why |
|---|---|---|
| samedi | sam-DEE | drop — only two consonants meet |
| vendredi | vahn-druh-DEE | keep — drd would collide |
| je ne sais pas | shay PAH | drop both; j assimilates to ch |
| la petite fille | lah p’teet FEEY | drop |
| une petite fille | ün puh-teet FEEY | keep — npt would collide |
| je te le donne | zhtuhl DON | alternate: drop, keep, drop |
In verse and in song the e caduc is pronounced far more often, because it is counted as a syllable — which is the whole basis of lesson 21.
Three facts that between them explain the French accent.
1. Stress is on the group, not the word. French puts a light lengthening on the final syllable of each rhythm group. Je vais à la gare has one stress: on gare. This is why English speakers sound choppy in French and French speakers sound flat in English — English stresses inside words, French at the edges of groups.
2. Syllables are equal and open. French prefers CV syllables and gives each roughly the same length. Ca-thé-drale, not ca-THEE-drul.
3. Emphasis moves to the front. The accent d’insistance stresses the first syllable of the word you care about, often doubling its consonant: C’est ABsolument faux ! · C’est ffformidable ! This is the one place French does stress a word — and using it is a quick way to sound much more natural.
| Pattern | Contour |
|---|---|
| Statement | rises across the middle groups, falls on the last |
| Yes/no question | rises to the end |
| Est-ce que / inversion question | may fall — the grammar already marks the question |
| Question word question | falls (Où tu vas ? descends) |
| List | each item rises, the last falls |
| Name | What it is | Example |
|---|---|---|
| un cuir | inventing a t liaison | « il a-t-un chien » (wrong) |
| un velours | inventing a z liaison | « moi-z-aussi » (wrong) |
| un pataquès | any botched liaison | « les-z-haricots » (wrong) |
| over-liaison | liaising across a boundary | « un enfant-z-adorable » (wrong) |
Take thirty seconds of a France Culture broadcast and transcribe it by syllable rather than by word — write down what you hear, with hyphens, before you try to identify the words. You will find your comprehension problem was never speed. Then read the same passage aloud, marking rhythm-group boundaries with a slash first.
Metropolitan French has been losing optional liaisons steadily for a century, and some once-obligatory ones are now unstable in speech. Politicians over-liaise deliberately as a marker of gravity; comedians imitate exactly that. Southern French keeps far more e caduc than Parisian — une petite table in Marseille has audible schwas where Paris has none — and that, rather than vowel quality, is what makes the accent du Midi immediately recognisable.
Québécois phonology adds features France does not have. Affrication turns t and d before i and u into ts and dz: tu dis sounds like tsu dzi. Long vowels are diphthongised (père → paèr), and final consonant clusters are simplified more readily than in France. Liaison rules themselves are the same, but Québécois speech drops the e caduc at least as aggressively as Parisian and often further.
Write oui or non.
Write the consonant you actually hear.
Write tombe (dropped) or reste (kept).
Write cuir, velours or h aspiré.
1. Liaison is blocked after et because:
2. Why is the e pronounced in vendredi but not in samedi?
3. Where does French put the stress in je vais à la gare?
